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 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. The item was made by an early pioneer and innovator of marine navigation and instrument making. Compass and Housing; the brass housing, with side light box, insides a fluid dampening gimble compass.

Navigators use parallel rule with maps and charts for plotting a specific course on a chart. One long edge is used with the compass rose on the chart, aligning the centre of the rose with the desired direction around the edge of the rose. The compass bars are then ‘walked’ in and out across the map to the desired location so that lines can be plotted to represent the direction to be travelled.

This model parallel map ruler is a good example of the commercial diversity of navigational instruments made by Kelvin & Hughes after World War II. It was made in numbers for use by shipping after the second world war and is not particularly rare or significant for it's type. Also it was made no earlier than 1947 as the firms of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd who took over from Smith & Sons were not amalgamated until 1947. It can therefor be assumed that this ruler was made during the company's transitional period to Kelvin & Hughes from Smith Industries Ltd.Brass parallel rule in wooden box with blue felt lining.Rule inscribed on front "Kelvin & Hughes Ltd" " Made in Great Britain"flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, parallel rule, kelvin & hughes ltd, map ruler, plot direction, navigation, maps, echo sounder, kelvin & james white, lord kelvin, baron kelvin of largs, scientific instrument

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.

The nautical compass is used for determining directions, using a free moving magnetised needle, indicating north and south. This is a medium sized compass and was suitable for mounting in a fixed brass binnacle or a portable wooden box. The compass fluid was typically lamp oil, or a mixture of alcohol and water. This compass, based on its pattern, was probably manufactured around the 1930s. The compass’s maker, Bergen Nautik, was a 20th Century compass manufacturer, making compasses from the 1900s but no longer in business.The factory was located in Hordaland County, Bergen, on the west coast of Norway. This compass is not a very significant marine item as it was made in the 20th century. Examples of the same compass that have been salvaged can be purchased today mounted either in a wooden box or a brass pedestal.Compass; marine or ship's compass, brass, gimbal mounting, in blue metal casing.

This sextant is very similar to a 1915 Sextant design. A sextant is an astronomical instrument used in measuring angular distances especially the altitudes of sun, moon and starts at sea determining latitude and longitude.This sextant is an example of a 19th-century marine instrument used for finding location at sea.

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.

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)"

Captain Robilliard: James Arthur Robilliard was a sea captain and tentmaker, born on the 19th April 1843 at Saint Helier, Jersey. He trained there in his father's sail loft as a sailmaker. His first job as a sailor was in Liverpool, England and 1875 James Robilliard migrated to Australia as mate on the "E.M. Young". James Robilliard and his family were amongst the early settlers that arrived along the Curdies River in the Heytesbury district of Western Victoria. In 1877 he became a Captain and would have used his compass from ship to ship. On 28th May 1877 in that same district a small 3-masted, schooner the "Young Australian" was wrecked. This schooner had been built 1864 at Jervis Bay, NSW. She had been on her way from Maryborough Queensland to Adelaide, under the command of Captain Whitfield, when she lost her mainmast in a heavy gale. She was beached at Curdies Inlet in Peterborough, Victoria, Captain Robilliard was placed in charge of the salvaging operation and recovered a good portion of the cargo. Not long after this incident a Warrnambool shop owner David Evans found employment for James Robilliard with Evan Evans, who produced tents, sails, tarpaulins and similar goods; James already had the necessary skills for this work. Evan Evans was the same sailor rescued from the “Young Australian” soon after his rescue Evan recalled he had a relative in Australia in a town called Warrnambool and while walking in Timor Street, Warrnambool, he saw a sign over a shop that said “David Evans” and once the two men met, Evan was warmly welcomed. David then helped his relative to establish a tent and tarpaulin-making business there. Evan later transferred his successful business to a shop in Elizabeth St, Melbourne, under the name Evan Evans Pty. Ltd.) James Robilliard, a committed Christian, and accredited Lay Preacher with the Methodist Church. He travelled around the local district leading the settlers in worship. On 14th November 1879, Captain Robilliard married Helen Beckett. Alfred and Selina Beckett and their family all attended the church at Brucknell where Captain Robilliard preached. He was said to have been taken by their young daughter Helen. James and Helen had ten children; James Arthur (Jnr), Henry William, Nellie Jessie, Alfred Albert, Rubena Nellie, De Jersy Norman, Clifford Beckett, Olive Ida, Frances Ridley Havergal and Nellie Elvie, all born in Victoria. In the 1880s James Robilliard captained the cutter "Hannah Thompson" into Port Campbell, Victoria. This vessel was the first coastal trader to operate between Melbourne and Port Campbell. At one time Captain Robilliard had to beach the "Hannah Thompson" for repairs. In 1923 she was blown ashore in a gale and wrecked at Oberon Bay, at Wilson's Promontory. In 1889 the compass was saved by Captain James Arthur Robilliard from his sinking brigantine "Mary Campbell" in 1889. This vessel was used to carry equipment for the Sydney Sugar Refinery's Mill in Southgate, NSW. The ship had been built in 1869 and traded for the next 20 years between Australian ports and rivers along the east coast as well as regular ports in New Zealand. She was recognised by the Sydney Morning Herald as one of the best "carrying vessel in the timber trade". She had several owners over this time, the last one being Captain James A. Robilliard. On 29th April 1889 the "Mary Campbell", with Captain James A Robilliard as captain and owner, was on her way from Clarence River, NSW to Melbourne, Victoria with a cargo of railway girders for the Melbourne Harbour Trust. Captain Robilliard encountered a storm off Port Macquarie. He sailed the vessel south to about 40km east of Cape Hawke, near Tuncurry. At around 7 pm, he discovered that the cargo had shifted during the storm and the heavy girders had damaged the hull, causing a leak. The pumps were inadequate to stem the fast-flowing leak water soon filled the hull during the next two hours. Some of the crew began throwing the cargo overboard to lighten the vessel, hoping to keep it afloat until daylight. When the water reached over 2 meters in the hull they realised their efforts were in vain. On the 30th April 1889, the crew left the vessel the ship was sinking fast, so they made for the shore. While still miles off Cape Hawke all seven crew members, including the Captain, were rescued by the Government Tug "Rhea" and taken to Port Macquarie Hospital and later returned to Sydney in the vessel "Wellington". No cargo had been saved and the consignment had been under-insured, only covered for half its value. The name of the last ship Captain Robilliard sailed is currently unknown, however, he sailed that ship from the port of Marlborough, Queensland, carting steel railway girders for the Geelong-to-Camperdown railway line. On this trip the ship hit a storm, the cargo shifted and the ship was wrecked along the NSW coast. After this, Captain Robilliard retired from the sea and began farming in Peterborough. In about 1897, verging on retirement, Capt. Robilliard superintended the Melbourne Sailors’ Home in Spencer Street, Melbourne, before being asked to leave this position in 1902 for trying to shut down a local hotel. On 6th May 1917 Captain James Arthur Robilliard J.P. died at Blackwood Park, in the Cobden district of Brucknell, the first Robilliard family homestead in Australia. He was buried in the Melbourne General Cemetery, Victoria. His wife Helen passed away in 1947. This compass, once belonging to Captain James Arthur Robilliard, is of local and state historical significance for its use by the Captain with his vessel the "Mary Campbell", a trading vessel that was bringing railway girders to the Melbourne Harbour Trust. He also used this compass on the "Hannah Thompson", listed on the Victorian Heritage Register and known as being the first coastal trader to operate between Melbourne and Port Campbell. The compass is also a very fine example of maritime navigational instruments manufactured and used in the mid-19th century. Marine compass, brass, in wooden box with separate, fitted lid. The compass card has sixteen points. The four principal points are marked; North with a star shaped, South with an “S”, East with and “E” and West with an “O” (French word OUEST). Each quadrant of the circle is numbered from 0 – 90 degrees. The card is floating in a liquid. The compass gimbal is attached to the sides of the box and to the front and back of the compass’ cylindrical brass frame. The mahogany coloured timber storage box is joined with brass nails. The centre of the lid has a folding decorative brass handle. The lid fits over base and closes with a brass screw and hook on both front and back.

An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

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 vessel's speed through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. Various manufacturers of nautical equipment had sought over the years to perfect the operation of determining a ship's speed and it wasn't until Thomas Walker and his son Ferdinand developed a mechanical system that eventually made this task became easy for marine navigators. Thomas Walker & Son were internationally renowned in the manufacturing of ship logs the founding father, Thomas Walker (1805–1871), an engineer in Birmingham, patented his mechanical log in 1878 which was a recording instrument that 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 then recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kickstarting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ship’s log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (a British-based organisation promoting ties and trade with the British Caribbean), being the most common log in use for two generations. It took until 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log (Trident) and the Walker factory was one of the first to introduce the 48-hour work week for employees.The ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades.Ships Log, Walker Trident electric motor, in wooden box with instructions inside box.

This compass is the type used by an artillery unit of the Australian Military Forces during World War 2 and made by J W Handley. Although having owned the factory site since 1935 at 657 Victoria St J W Handley began to produce various items for the Australian Military forces after purchasing and expanding the factory to 655 Victoria St. It appears that he, or some one else may already have been occupying the site for industrial purposes, such as (Manufacturing, Foundry and Electroplating) since at least 1929. J W Handley Pty Ltd was actively producing items for the Military during the war years, a newspaper article from 1939 shows the factory in production and employing 420 people during 1939. J W Handley after the war moved into producing other non military items including a range of fishing reels. The company ceased trading in 1987 and was deregistered as J W Handley Pty Ltd in 1990.The item demonstrates the industrial capability of Australia at the start of World War 2, this item is actively sort by collectors of Australian Military memorabilia and represents a time in Australian history when the country was at war and the general population was concerned about an invasion from Japanese forces. It also therefor is of social significance as many Australians served in the Military forces at that time and the item is complete and in very good condition.A plane table compass, sometimes referred to as a trough compass, used by surveyors and artillery crew to accurately establish magnetic north. The compass is precision machined of brass material with a long needle to ensure accuracy. The compass scale is marked with a centre zero (for magnetic north) and graduations indicating plus and minus five degrees. The compass is housed in a protective wooden case with a sliding lid.

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.

A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or "points".

The sculptural installation was a gift from the Portuguese government and presented to Warrnambool City Council. The sculptor, Jose Nuncio, completed the work in 1999, and it was inaugurated at Warrnambool in 2001. Prince Henry the Navigator founded a school of navigation in Sagres, Portugal. This led to navigation techniques that made the 15th century voyages of discovery possible. The vision of Prince Henry brought together ship builders, cartographers, instrument makers and mathematicians. Vasco de Gama rounded the southern tip of Africa and sailed across the Indian Ocean to India in 1496. This started a new era of trade and exploration, expanding the boundaries of the known world, and linking the east with west.Six colour photographs of a sculptural installation at Warrnambool.

William Thomson described a new "Marine Azimuth Mirror" at the 1877 meeting of the British Association for the Advancement of Science, and patented the design in Britain and the U.S. This instrument is an example of the improved design, with a reflecting prism in place of the original mirror. Thomson introduced this form in the early 1880s. The signature indicates that it was made during the period 1900-1913. A child prodigy, William Thomson went to university at the age of eleven. At twenty-two he was appointed Professor of Natural Philosophy in Glasgow where he set up the first physics laboratory in Great Britain and proved an inspiring teacher. He primarily researched thermodynamics and electricity. On the practical side he was involved in the laying of the Atlantic telegraph cable. He was also the partner of a Glasgow firm that made measuring instruments from his own patents.An instrument of significant importance which made marine navigation easier and more accurate in the early twentieth century.An Azimuth mirror with wooden box.Kelvin & Hughs Ltd Serial No - illegible Made in Great Britainazimuth mirror, william thompson, lord kelvin, naviagtion, marine instruments

Various artifacts from the steamship 'Wattle'. The Steam Tug Wattle, a steel ship, was built as a harbor tug in 1933. Steam is supplied from a two-furnace Scotch Marine wet-back boiler which was originally fired with dewatered and filtered waste oil but has recently been converted to burn distillate for environmental and maintenance reasons. It was launched at Cockatoo Island on 27 June 1933 by Cockatoo Docks & Engineering Co. Ltd. (CODECO) on order from the Commonwealth Shipping Board. Now fully restored it operates excursions in Port Phillip and the Yarra.Solar Reflector with spirit level in wooden boxst wattle, navigational intruments
