In 1941, the scientific instrument manufacturing firms of  Henry Hughes & Son Ltd, London, England, and  Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.

This Dollond Day or Nigh telescope was designed to be used in any light conditions, as its name implies. Telescopes are optical instruments designed to make objects appear to be larger or closer. The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation.    John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that is represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollond's early library telescopes. Its connection with one of England's 18th century pioneers in optical development makes it a significant and an important item to have within the collection.Telescope: Dollond's Telescope, Day or Night model navigational instrument.

From Scarborough Maritime Heritage Centre: A Yacht Log was a nautical instrument for measuring a vessel's speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat's speed and distance travelled to determine its position at sea. In times past the only way to measure a ship's speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this they could estimate the speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. In 1878, Thomas Ferdinand Walker (1837–1921), an engineer in Birmingham, patented a mechanical log in which a recording instrument was attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. The 'Log' at the Heritage Centre was recovered from a skip in Scarborough and was one of the first artefacts collected by the volunteer group. It is made of brass with a ceramic dial, with the main scale marked from 0 to 100 nautical miles and an inset dial marked from 0 to 10 miles. It has a fixing plate, on which it can turn, with which it would have been attached to the 'taffrail', the rail at the stern of a ship, usually on the starboard side. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Its exact date of manufacture cannot be determined but this design was manufactured in the first half of the 20th century. These mechanical logs have now been superseded by electronic equipment such as GPS navigation instruments.This instrument was made by a significant nautical instrument manufacturer and demonstrates the innovation needed at the time for improved navigation and safety at sea.Timber Box containing an instrument for measuring speed and distance. There is a brass, cased log with a white enamel dial. It also includes a towing cord and cylindrical rotator. The box has paper labelling on the front and also the inside of the lid. The label on the inside of the lid has instructions for use. Although the lid is hinged it has broken off and is separate. The hinges remain attached.Enamel Dial: Walkers Patent Excelsior Yacht Logmaritime, maritime history, tool, navigational tool, navigational instrument, navigation, sailing, walkers, maritime technology, walker & son

A sextant is an astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, especially the altitudes of the sun, moon, and stars. It is a doubly reflecting navigation instrument and used mainly by sailors to measure the angular distance between two visible objects. The name comes from the Latin sextans, or “sixth part of a unit,” because the sextant’s arc can be 60° or 120° of a circle depending on the model used. The primary use was to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. This angle and the time when it was measured is used in order to determine Greenwich Mean Time and hence longitude. Sighting the height of a landmark on land can also give a measure of distance from that object. History: The development of the sextant was as an improvement over the octant, an instrument designed to measure one's latitude. The octant was first implemented around 1731-present but can only measure angles up to 45°. As larger angles were needed to allow the measurement of lunar objects - moon, stars and the sun - at higher angles, the octant was superseded by the sextant. The sextant is a similar instrument but better made and allows larger angles from 60° to 120°. This improvement allows distances to be accurately calculated thereby giving longitude when used with a chronometer. The sextant was derived from the octant in 1757, eventually making all previous instruments used for navigational positioning obsolete. The sextant had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. It should be noted that the octant and quadrant are in the same family as they were, and all are, regarded as sextants. The sextant is representative of it's type and although not fully complete it demonstrates how 18th,19th and 20th century mariners determined their latitude and longitudinal to determine their position on a chart, allowing them to navigate there way across the world's oceans. It also demonstrates the skill and workmanship of the early instrument makers that operated scientific instrument businesses from London and other areas of England to provide most of the navigational instrumentation used by commercial and military navies of the time.Sextant with square, fitted box of polished wood, "Hezzanith" brand.

An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.

This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. John Browning was particularly well known for his scientific advances in the fields of spectroscopy, astronomy, and optometry. Between 1856 and 1872, Browning acquired provisional patents for designs of numerous scientific instruments. He was also the recipient of an award at the 1862 International Exhibition held in London. Also recognised for his temperature-compensated aneroid barometer. Browning's scientific instruments were used in physics, chemistry, and biology. The products he designed and manufactured included spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmologist, and electrical equipment such as electric lamps. John Browning was born around 1831 in Kent, England. His father, William Spencer Browning, was a maker of nautical instruments. John Browning's great-grandfather was also an instrument maker as well as John’s brother Samuel Browning of the firms Spencer & Browning and Spencer, Browning & Rust, who also manufactured navigational instruments. The latter firm was in operation in London from 1784 to 1840 and was succeeded by the firm of Spencer, Browning & Co. John Browning initially intended to follow the medical profession and entered Guy's Hospital, a teaching hospital and a school of medicine. Despite having passed the required examinations, however, he abandoned his plans. Instead, he apprenticed with his father, William Spencer Browning. At the same time, in the late 1840s, he was a student attending the Royal College of Chemistry several days per week. By the early 1870s, practical optics had become John Browning's primary interest, and he listed his occupation as an optician on the census records from 1871 to 1901. He was well known among London's ophthalmic surgeons for his various ophthalmic instruments. He had a large part in reforming the art of crafting spectacles. Other achievements were as an author of the book, How to Use Our Eyes and How to Preserve them by the Aid of Spectacles. Published in 1883, the book included thirty-seven illustrations, including a diagram demonstrating the anatomy of the eye. In 1895, he was one of the founders of the "British Ophthalmology" the first professional organisation for optometry. He was not only its first president but also registered as its first member so many considered him to be the first professional optometrist. Other professional organisations he belonged too was as a member of “The Aeronautical Society of Great Britain”. In 1871 constructing the first wind tunnel located at Greenwich Marine Engineering Works. He was also a member of other scientific organisations, such as the “Microscopical Society of London”, the “Meteorological Society”, and the “Royal”. Then in 1908 the company of W. Watson & Son, opticians and camera makers, took over John Browning's company since 1901 John Browning had been semi-retired but in 1908 he fully retired and moved to Bournemouth in Hampshire. He died in Cheltenham, Gloucestershire in 1925.The telescope is significant for its association with one of the world’s leading scientific instrument makers and inventor of the 19th and early 20th century. It is believed the donation came off a wreck either in Port Philip Bay or between Point Lonsdale and the Nepean Heads making it a significant maritime historical artefact. Its provenance is good given it was taken off a wreck in this area by the Point Lonsdale lighthouse caretaker. Examples of John Browning's telescopes because of their scientific and historical importance are highly valued by collectors.Marine style single draw brass telescope with a sunshade.

This compass was used to determine directions using a free-moving magnetised needle, indicating north and south. W Hartmann was a compass maker located in Hamburg Germany some of his compasses are marked “Gehna” and “Nautica”. There is no information available regards W Hartmann, his successor in the business was “Georg Hechelmann” a marine instrument maker of which Gehna is an acronym of his name. In 1874 he patented an improved version of “Lord Kelvin Thomson’s” compass design of a paper rose with magnets hung on silk threads. It appears he worked in his shop from around 1878 until probably 1905. The company he founded "Gehna" is today a substantial international marine corporation and is still based in Hamburg. A rare example of an early binnacle and compass probably used on a sailing vessel. It is a significant item not only for it’s rarity but also because it demonstrates the progress of marine navigational instrument development in the late 19th century.

A telescope is an optical instrument used to make distant objects appear nearer and larger, this item is small enough and designed to be portable enough to fit into a gentleman's pocket while out walking. This type, size and manufacture of the telescope was designed for general everyday use for bird watching and general observation of subjects while out walking. This item was not for marine use as its focal length is too short and could only observe subjects that were not too far away. Also, its size indicates telescopes of this type are pocket telescopes.This telescope is significant for its probable association with leisure activities of a person in the 19th century for leisure purposes such as bird watching, horse events and ship spotting.Three draw brass hand held telescope, folding.Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, telescope, folding telescope, navigational instrument, optical instrument, pocket telescope, leisure, brass telescope, hobby

Negretti and Zambra 1850-1980s were optical instrument makers and mathematical instrument makers based in London, England. The firm of Negretti and Zambra was established in 1850 by Henry Negretti and Joseph Zambra who had formed a partnership. Their skill was immediately apparent when exhibiting at the 1851 Great Exhibition at Hyde Park, they were the only English instrument makers to receive a prize medal for meteorological instruments, resulting in their appointment as instrument makers to the queen, Greenwich observatory, and the British Meteorological Society. In 1853, when the Crystal Palace was re-erected in Sydenham, Negretti and Zambra became the official photographers of the Crystal Palace Company, which allowed them to photograph the interior and grounds of the new building. The firm made use of this access to produce a number of stereographs. Between 1855 and 1857 Negretti and Zambra commissioned photographer Pierre Rossier to travel to China to document the Second Opium War. Although Rossier subsequently was unable to accompany to Anglo-French forces in that campaign, he nevertheless produced a number of stereographs and other photographs of China, Japan, the Philippines and Siam (now Thailand), which Negretti and Zambra published and that represented the first commercial photographs of those countries. In 1856 Negretti and Zambra sponsored a photographic expedition to Egypt, Nubia and Ethiopia conducted by Francis Firth. In 1864 Negretti and Zambra (themselves) photographed Shakespeare's House at Stratford on Avon. A sepia photograph was then pasted onto card 4" × 2.5". This was then presented to visitors to the Crystal Palace to enable them to compare it with the model erected by Mr E. T. Parr in the Centre Transept. The card itself is headed "Crystal Palace April 23rd 1864." That year they also published a book, titled A Treatise on Meteorological Instruments, (which was reprinted in 1995). Throughout World War One Negretti and Zambra were entirely engaged in the production of various instruments for the Ministry of Munitions. They developed many instruments for the Air Ministry including a mercury-in-steel distance thermometer for taking the oil and air temperatures in aircraft which was patented in 1920. In 1946 the company went private and in 1948 the company was made public, and by 1950 Negretti and Zambra had 821 employees in Britain. In order to increase production and to safeguard future development in 1964, they purchased a modern factory at Aylesbury for all their production. In 1981 Negretti and Zambra were taken over by a group of financial institutions in the form of Western Scientific Instruments and in 1985 the company was acquired by Meggitt Holdings.The subject compass is just one type of the many marine and scientific, optical items this company produced over it’s life time. Negretti and Zambra were prolific manufactures of types of items as well as being very prominent in photography pioneering new innervation's and sponsoring expeditions to little known countries to document peoples daily lives and culture through photography.Azimuth compass on tripod in a fitted wooden box with a round spirit level included, lid of box has three indented circles where the legs of the compass fit when it is set up for use.

First State Watch Factory: This factory was founded in 1930 under orders from Joseph Stalin, the "First State Watch Factory" was the first large-scale Soviet watch and mechanical movement manufacturer in the USSR. Via its USA-based trading company (Amtorg), the Soviet government bought the defunct Ansonia Clock Company of Brooklyn, New York in 1929, and the "Dueber-Hampden Watch Company of Canton", based in Ohio. The soviets moved twenty-eight freight cars full of machinery and parts from the USA to Moscow in order to establish the factory. Twenty-one former "Dueber-Hampden" watchmakers, engravers and various other technicians helped to train the Russian workers in the art of watchmaking as part of the Soviet's first five-year plan. The movements of very-early products were still stamped "Dueber-Hampden, Canton, Ohio, USA" (examples of these watches are very collectible today). In 1935 the factory was named after the murdered Soviet official Sergei Kirov. During the second world war, as the Germans closed in on Moscow in 1941, the factory was hurriedly evacuated to (Zlatoust USSR). By 1943 the Germans were in retreat, and the factory was moved back to Moscow, adopting the "First Moscow Watch Factory" name. In 1947 the first wristwatches under the brand name "Pobeda" and the first Marine Chronometers and Deck watches were produced. By 1951 the production of wristwatches had increased to 1.1 million. In 1975 new machinery and equipment for manufacturing complex watches were imported from Switzerland. The first chronograph called "Okean" (3133) was produced for the space station "Soyuz-23."The Chronometer is of recent manufacture and an excellent example of the type of instrument used to navigate the seas in the 19th century. It is of good quality and of a type regarded as very accurate and well made. The maker, First Watch Factory, has a dept that is still producing the "8916" standard Chronometer for horologists and collectors.

The ship’s telegraph section was once part of the navigational equipment of the famous paddle steamer, PS Hygeia, and was later installed on Flagstaff Hill’s exhibit, the steamer Rowitta. This is the Bridge Section of a ship’s telegraph, a Duplex Gong model, made by Chadburn & Son of Liverpool. The gong sounded two signals whenever the navigational commands to change the speed or direction were given by the ship’s pilot. Communication between the ship’s pilot and the engine room in the late 19th to the mid-20th centuries was made with a system called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The equipment has two parts, the Bridge Section and the Engine Room Section. The Bridge Section was usually mounted onto a pedestal, and the Engine Room Section was attached to a vertical surface. The standard marine commands were printed or stamped around the face of the dial and indicated by a pointer or arrow that was usually moved by a rotating brass section or handle. The ship’s pilot stationed on the Bridge of a vessel sends his Orders for speed and direction to the Engine Room with the E.O.T. He moves the lever or levers, depending on the number of engines the ship has, to change the indicator on the Bridge Section’s dial to point in the new direction and speed of travel. This change causes the Orders to be duplicated on the Engine Room Section’s dial and a bell or bells to signal the change at the same time. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. CHADBURN & SON, Liverpool- Chadburn Brothers, William and C.H., were joint inventors and well-established makers of optical and scientific instruments and marine gauges. The firm was granted the Prince Albert Royal Warrant in the late 19th century. In 1870, William Chadburn applied for a patent for his navigational communication device for use on ships. By 1875, Chadburn & Son was producing the brass Engine Order Telegraph in its plant at 71 Lord Street, Liverpool. In 1911, the ship, RMS Titanic, was launched, fitted with Chadburn & Sons E.O.T. The Chadburn Ship Telegraph Company Limited was registered in 1898 to take over Chadburn & Sons. In 1903, a large factory at Bootle, near Liverpool, and its products were being sold overseas. In 1920, electric-powered telegraphs were developed. In 1944, the name changed to Chadburn’s (Liverpool) Limited. In 1968, the company became Chadburn Bloctube Ltd. In 2000, the company, now Bloctube Marine Limited, was still manufacturing ship telegraphs. The P.S. HYGEIA 1890-1932: - This ship’s telegraph was installed on the new paddle steamer, PS Hygeia, one of three iconic pleasure steamers famous for providing regular services in Port Phillip Bay, Victoria, to thousands of passengers between the ports of Queenscliff, Sorrento, Portsea, Dromana, Rosebud, Rye, and Mornington. It joined the Ozone and the Weeroona, all three described as being glamorous, powerful and fast. Its ticket office was on the pier itself. The P.S. Hygeia was built in Yorker, Scotland, in 1890, by Napier, Sharks & Bell. It was registered in Melbourne, Australia, by Hubbart, Parker & Co. in 1891. The steel ship was 92 metres long, able to travel at 22 knots, and licensed to carry over 1600 passengers in luxury, with even a barber shop on board. The regular service between the ports in Port Phillip Bay, Victoria, continued for over 40 years. With the decline in passenger demand, the service wound down. The Hygeia was sold to H.M. Morris in 1931 for demolition and breaking up. Equipment, fittings, and even lifebuoys were sold, with many items purchased by people who had some connection to the Hygeia. On August 25th, 1931, what was left of the vessel departed Port Melbourne and eventually, in June 1932, it was laid to rest at the ships’ graveyard outside Port Phillip Heads. The SS ROWITTA 1909-2015: - The ship’s telegraph was originally installed on the PS Hygeia. It was purchased when the Hygeia was broken up in 1931 and later installed, in 1975, on Flagstaff Hill’s SS Rowitta, an exhibit greatly enjoyed by the public until it was demolished in 2015. The ferry “SS Rowitta” was built in 1909 in Hobart, Tasmania. The timber steam ferry was built using planks of Huon and Karri wood. It was a favourite with sightseeing passengers steaming along Tasmania’s Tamar and Derwent rivers for 30 years. Rowitta was also known as Tarkarri and Sorrento and had worked as a coastal trading vessel between Devonport and Melbourne, and Melbourne, Queenscliff and Sorrento. The vessel had given over 100 years of service and pleasure. This Bridge section of a ship’s Engine Order Telegraph, used with an Engine Room section, represents late-19th-century change and progress in communication and navigation at sea. This type of equipment was still in use in the mid-20th century. It is significant for its association with its maker, Chadburn & Son, of Liverpool, a well-known marine instrument maker whose work was recognised by English Royalty, and whose products were selected to supply similar equipment for use on the RMS Titanic. The ship’s telegraph is also significant for its association with the paddle steamer PS Hygeia, one of three iconic steamers that transported thousands of passengers from port to port within Port Phillip Bay, Victoria, for over 40 years from the 1890s to the 1930s. Queenscliff Borough remembers the Hygeia by naming a road near the pier Hygeia Drive. The Hygeia is registered on the Victorian Heritage Database as a vessel of significance, VHR S329. In 1901, Hygeia had the privilege of carrying their Royal Highnesses, the Duke and Duchess of York, from Mornington to St Kilda Pier, Melbourne, during their Royal visit celebrating the Federation of Australia. The ship’s telegraph is also important for its connection with the Rowitta, a large exhibit on display at Flagstaff Hill Maritime Village, aiding maritime education for over 40 years. It represented the importance of coastal traders to transport, trade and communication along the coast of Victoria, and before the availability of rail and motor vehicles, serving many roles. Bridge section of a Ship’s Telegraph or Engine Order Telegraph (E.O.T.). The round, double-sided, painted glass dial is inside a brass case behind glass. It is fitted onto an outward tapering brass pedestal with a round base. The brass indicator arrows between the handles point simultaneously to both sides of the dial when moved. An oval brass maker’s plate is attached to the top of the case. The dial’s faces have inscriptions that indicate speed and direction, and the front face and plate include the maker’s details. A serial number is stamped on the collar where the dial is fitted to the pedestal. The ship’s telegraph is a Duplex Gong model, made by Chadburn & Son of Liverpool.

The John E. Hand & Sons Company was founded in Philadelphia in 1873, quickly gaining a reputation as competent manufacturers of nautical instruments and compass adjusters. In fact, John Enos Hand, the company founder, is recognised as the first man in America to adjust a compass aboard an iron ship. The Hand Company built navigational equipment for all varieties of floating vessels, and operated a chain of retail outlets with “service stations” in numerous port cities, including Baltimore and New Orleans, until 1956. Service stations sold Hand instruments as well as other nautical paraphernalia and provided compass adjusting services. Additionally, John E Hand and his two sons, John L Hand and Bartram Hand, were inventors in their own right who patented design improvements for numerous instruments that were employed in the company’s work. Commercial and private contracts dominated the firm’s business until the late 1930s when the United States military began preparations for World War II. Although the Hand Company never completely abandoned its involvement with private industry, after World War II, military contracts monopolised their business. The Company obtained contracts with the Navy, Coast Guard and Marines to develop new instruments, and to build military-engineered nautical equipment. Of note are the wrist compass, developed for the Navy beginning in the 1950s, and the Mark VII Model 5 Navy Standard Binnacle. Although it moved numerous times, the Hand Company headquarters and factory remained in the Delaware Valley, occupying several buildings in Philadelphia and southern New Jersey. Maintaining its central office in Philadelphia well into the 1900s, the factory was moved to Atco, New Jersey around the turn of the twentieth century and subsequently to Haddon field, New Jersey. It moved one last time in the 1960s to Cherry Hill, New Jersey. In 1997, California-based Sunset Cliffs Merchandising Corporation purchased the Hand Company and all its assets for $100,000. "HAND" brand taffrail log by John F. Hand and Sons Co.

The ship's log part, called a fish, is likely to be from a mechanical taffrail log system. It was recovered from the wreck site of the barque, the 1840-1852 Grange. There are no marks on the fish to identify its maker or model. It is part of the John Chance Collection. This ‘fish’ is part of an early to mid-1800s ship's log. It would likely have been part of a taffrail log connected to a rotor (also called propeller, spinner) by a strong line, and the other end connected by a line to a dial mounted on the taffrail, or stern rail, at the stern of the vessel. As the propeller rotated through the water it would spin the log, which in turn would cause a number to register on the dial, showing the current speed in knots; one knot equals one nautical mile per hour. TAFFRAIL LOGS A taffrail log is a nautical instrument used for measuring the speed of a vessel, providing vital navigational information to be calculated, such as location and direction. A log has been used to measure the speed of a vessel since the 1500s. A simple piece of wood was tied to a long line and thrown into sea at the back of the vessel. The rope was knotted all along at equal distances apart. On a given signal the log line was pulled back into the vessels, the knots counted until the log came up, then the figures were calculated by a navigator In 1802 the first successful mechanical log available for general use was invented by Edward Massey. It had a rotor 'V' section connected to a recording mechanism. The water’s movement rotated the rotor, which intern sent the movement to the recorder. There are examples of this invention available to see in some of the maritime museums. Thomas Walker, nephew of Edward Massey, improved on Massey’s design, and Walker and his son took out a patent on the A1 Harpoon Log. In 1861. Both Massey and Walker continued to improve the designs of the taffrail log. New designs were still being introduced, even up to the 1950s. THE GRANGE, 1840-1858- The wooden barque ’Grange’ was a three-masted ship built in Scotland in 1840 for international and coastal trade. On March 22, 1858, the Grange set sail from Melbourne under Captain A. Alexander, carrying a cargo of ballast. The barque had left the Heads of Phillip Bay and was heading west along the Victorian coast towards Cape Otway. The ship struck Little Haley’s Reef at Apollo Bay due to a navigational error and was stuck on the rocks. The crew left the ship carrying whatever they could onto the beach. Eventually, the remains of the hull, sails and fittings were salvaged before the wreck of the Grange broke up about a month later. About 110 years later, in 1968, the wreck of the Grange was found by divers from the Underwater Explorers Club of Victoria. They were amazed to find a unique, six to nine pound carronade (type of small cannon) and a cannonball on the site. There have been no other similar carronades recorded. In that same year the anchor of the Grange was recovered by diver John Chance and Mal Brown. The ship’s log is significant historically as an example of hardware used when building wooden ships in the early to mid-19th century. The ship’s log is historically significant as an example of the work and trade of blacksmith. The ship’s log also has significant as it was recovered by John Chance, a diver from the wreck of the Grange in the 1968. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The ship’s log is historically significant for its association with the 1840s wooden barque, the Grange. The Grange is an historical example of a Scottish built vessel used for international and coastal trader of both cargo and passengers in the mid-19th century. The Grange is an example of an early ship, designed with a wooden hull. It is significant as a ship still available to divers along the south coast of Victoria, for research and education purposes. The Grange is an example of a mid-19th century vessel that carried a weapon of defence onboard. Ship log fitting, called a fish; part of a brass navigational instrument, likely to be from a taffrail log. The metal is a tan colour and has rough surface with a sheen, and discolouration in places. Its basic shape is a hollow cylinder with ends tapering to a smaller size. In the centre there are opposing openings cut out, showing a rough texture inside. One end on the cylinder is closed with a ring and shank installed, fixed by an embedded screw through the end of the cylinder.

Bubble Sextant model Mark 1XA type A.M. 6B/218 in protective storage box. Complete, with operation instructions. This is an aviation navigation instrument used by the RAF and RAAF during the World War 2 era. A sextant is used to measure the altitude of celestial bodies above a horizontal line of reference. A navigator can use the horizon as this line of reference, but when an aircraft is above the clouds or flying at night, the navigator can’t see the horizon. The bubble sextant solves this problem by providing an artificial horizon.The storage case has a label with the following: "A.M. 6B/218 MK IX A" and the number "10772/42 (V)"

A prismatic compass is a common navigation and surveying instrument which was used extensively by the Forests Commission The compass most commonly used to run a traverse line. The compass calculates bearings of lines with respect to magnetic needle. A magnetic deviation correction was needed to convert the reading to a true bearing The compass could also determine angles between the traverse and waypoints (such as hilltop features). Commonly used for navigation. Largely replaced by modern GPS technology.Ex Army WW2 prismatic compass with leather case and strap.

The lead line or hand lead is a simple navigational instrument used as a depth finder to measure the depth of water under the ship’s keel and to take samples of the sea bed. The long line may be marked at regular intervals with tags of different coloured and textured fabric, such as rope, leather and cloth. Each tag was a code to represent a certain depth. The leadsman’s eyes and hands could distinguish the depth easily as he drew in the lead line, day or night and in poor weather conditions. A standard set of codes for the tags was used so that the depth of the sea could be easily and quickly read. The measurement used was a Fathom, which equals 1.83 metres. The codes were: - 2 fathoms = 2 strips of leather 3 fathoms = 3 strips of leather 5 fathoms = white duck fabric 7 fathoms = red bunting fabric 10 fathoms = leather with a hole 13 fathoms = blue serge fabric 15 fathoms = white duck fabric 17 fathoms = red bunting 20 fathoms = 2 knots The lead weight could be between 7 -14 pounds (3.5 – 6.5kg) and the rope would be approximately 25 fathoms (45m). The hollowed-out end of the weight would hold a stick substance such as tallow or wax, which would pick up samples from the sea bed which would show whether the vessel was close to, or far away from, the shore. The leadsman would stand at the front of the vessel and cast the lead line into the sea. When it hit bottom he would note the tag marker nearest the surface of the water and call out his finding. Then he would haul it up again and examine the kind of matter that adhered to the end of the weight, whether it be sand, mud, gravel, or the colour of it. This information would be given to the ship’s helmsman or navigator and would help indicate the proximity to the land.This handheld lead is an example of early marine navigational equipment used by sailors to travel the seas to measure the depth of the water and sample the nature of the seabed. It helps to understand the history and progress made from the very basic to the sophisticated technology of today.Lead line, sounding line or depth finder. The long length of rope has a heavy lead weight attached to the end. Coloured fabric tags are tied onto the rope at regular intervals, representing different depths. The concave base of weight holds sticky substances such as tallow or beeswax, providing an adhesive surface to collect samples of sea bed like sand, shells or pebbles. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, lead line, depth finder, hand lead, sounding lin, leadsmane, navigation instrument, leadline, hand lead line

An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or "one-eighth of a circle," for the Octan'ts arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for celestial navigation. The estimation of this angle, is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. This fine octant once belonged to Captain Farquhar Chisholm and was donated by his granddaughter, Margaret Ruth Greer (nee Chisholm, born 1914). The label inside the Octant's box reads “Thomas L. Ainsley, Instrument Maker … etc”. Farquhar Chisholm was born in 1832 in Inverness, Scotland. He regularly sailed on perilous voyages between Quebec, Canada and the Baltic ports of Europe. In 1854 he migrated to Australia during the Gold Rush, to a place called Fiery Creek (near Beaufort Victoria) where he was fairly successful in his quest for gold. In the years of the Great Gold Rush, it was said that there were over 40,000 diggers in the goldfields of the Beaufort area! In 1857 having made sufficient money, he hired another crew and returned to Clachnacuddin, Inverness shire, Scotland and in that same year, he studied and obtained his Master Mariner Certificate (which would have included the use of an octant for navigation). He was appointed to Mr George (or James) Walker, as commander of his sailing ship, the 3-masted ELIZABETH, built 1859 and known as “The Walker barque”. In 1870 he married, then in 1887 returned to Australia with his wife and children (Kenneth Chisholm (1871), Mary Bremner Chisholm (1873), Margaret Hood Chisholm (1874), Farquhar Chisholm (1878)). They arrived in Port Melbourne, Victoria and sadly, only six weeks after landing, his wife Caroline passed away (in Geelong,1888). In 1900 Capt. Chisholm lived in Camperdown (Victoria) and not long after this his daughter Margaret died of consumption. In his later years, he went to live in the manse of St. Paul’s Presbyterian Church, Wangaratta, with his son, Rev. Farquhar Chisholm. He died there on Sat, 23rd March 1912, 80 years old. He was known as “… quiet, unobtrusive and competent, respected by all with whom he came in contact”. Some other members of Captain Chisholm’s family are; his older son Kenneth Chisholm, who was a contractor in Camperdown; a nephew Donald Macintosh (of 23 Douglas Row, Inverness); a grandson Brian Jones (son of Caroline Belle-Jones nee Chisholm, who lived in Camperdown in the earlier part of her life).The octant, the forerunner of the sextant, was a significant step in providing accuracy of a sailors latitude position at sea & his vessels distance from land when taking sightings of land-based landmarks.Octant, once belonging to Captain Farquhar Chisholm.

This pair of altar lights is from the St. Nicholas Seamen’s Church, 139 Nelson Place, Williamstown, Victoria, and was used during religious services there. The Church was operated by the Mission to Seamen organisation. The par of candlesticks was originally donated by Mrs. R.J. Ewart,as part of the furnishings for the new St Nicholas Seamen's Church in Williamstown, opened in 1944. The candlesticks were made by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments. Thomas Gaunt photograph was included in an album of security identity portraits of members of the Victorian Court, Centennial International Exhibition, Melbourne, 1888 THE MISSIONS TO SEAMEN (Brief History: for more, see our Reg. No. 611, Set of Pews) The Missions to Seamen, an Anglican charity, has served seafarers of the world since 1856 in Great Britain. It symbol is a Flying Angel, inspired by a Bible verse. Today there are centr4es in over 200 ports world-wide where seamen of all backgrounds are offered a warm welcome and provided with a wide range of facilities. In Victoria the orgainsation began in Williamstown in 1857. It was as a Sailors’ Church, also known as ‘Bethel’ or the ‘Floating Church’. Its location was an old hulk floating in Hobson’s Bay, Port of Melbourne. It soon became part of the Missions to Seamen, Victoria. In the year 2000 the organisation, now named Mission to Seafarers, still operated locally in Melbourne, Portland, Geelong and Hastings. The Ladies’ Harbour Lights Guild was formed in 1906 to support the Missions to Seamen in Melbourne and other centres such as Williamstown. Two of the most significant ladies of the Guild were founder Ethel Augusta Godfrey and foundation member Alice Sibthorpe Tracy (who established a branch of the Guild in Warrnambool in 1920). The Guild continued its work until the 1960s. In 1943 a former Williamstown bank was purchased for the Missions to Seaman Club.

This pair of altar lights is from the St. Nicholas Seamen’s Church, 139 Nelson Place, Williamstown, Victoria, and was used during religious services there. The Church was operated by the Mission to Seamen organisation. The par of candlesticks was originally donated by Mrs. M. Jackson, as part of the furnishings for the new St Nicholas Seamen's Church in Williamstown, which opened in 1944. The candlesticks were made by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods, including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments.

In Victoria the orgainsation began in Williamstown in 1857. It was as a Sailors’ Church, also known as ‘Bethel’ or the ‘Floating Church’. Its location was an old hulk floating in Hobson’s Bay, Port of Melbourne. It soon became part of the Missions to Seamen, Victoria. In the year 2000 the organisation, now named Mission to Seafarers, still operated locally in Melbourne, Portland, Geelong and Hastings. The Ladies’ Harbour Lights Guild was formed in 1906 to support the Missions to Seamen in Melbourne and other centres such as Williamstown. Two of the most significant ladies of the Guild were founder Ethel Augusta Godfrey and foundation member Alice Sibthorpe Tracy (who established a branch of the Guild in Warrnambool in 1920). The Guild continued its work until the 1960s. In 1943 a former Williamstown bank was purchased for the Missions to Seaman Club.
