John B ...Langlands Company History: Langlands foundry was Melbourne's first foundry and iron shipbuilder established in 1842, only 8 years after the founding of the Victorian colony by two Scottish immigrants, Robert Langlands and Thomas Fulton, who had formed a partnership before emigrating (1813–1859). The business was known as the 'Langlands Foundry Co'. Henry Langlands (1794-1863), left Scotland in 1846 with his wife Christian, née Thoms, and five surviving children to join his brother Robert. By the time he arrived in early January of 1847 the partnership of Robert Langlands and Fulton had dissolved as Fulton had gone off to establish his own works. It was at this time that the two brothers took over ownership of Langlands foundry. Several years later Robert retired and Henry became sole the proprietor. The foundry was originally located on Flinders Lane between King and Spencer streets. Their sole machine tool, when they commenced as a business, was a small slide rest lathe turned by foot. In about 1865 they moved to the south side of the Yarra River, to the Yarra bank near the Spencer Street Bridge and then in about 1886 they moved to Grant Street, South Melbourne. The works employed as many as 350 workers manufacturing a wide range of marine, mining, civil engineering, railway and general manufacturing components including engines and boilers. The foundry prospered despite high wages and the lack of raw materials. It became known for high-quality products that competed successfully with any imported articles. By the time Henry retired, the foundry was one of the largest employers in Victoria and was responsible for casting the first bell and lamp-posts in the colony. The business was carried on by his sons after Henry's death. The company was responsible for fabricating the boiler for the first railway locomotive to operate in Australia, built-in 1854 by Robertson, Martin & Smith for the Melbourne and Hobson's Bay Railway Company. Also in the 1860s, they commenced manufacture of cast iron pipes for the Board of Works, which was then laying the first reticulated water supply system in Melbourne. Langlands was well known for its gold mining equipment, being the first company in Victoria to take up the manufacture of mining machinery, and it played an important role in equipping Victoria's and Australia's first mineral boom in the 1850s and 1860s. Langlands Foundry was an incubator for several engineers including Herbert Austin (1866–1941) who worked as a fitter at Langlands and went on to work on the Wolesely Shearing machine. He also founded the Austin Motor Company in 1905. Around the 1890s Langlands Foundry Co. declined and was bought up by the Austral Otis Co. in about 1893. History for Grimoldi: John Baptist Grimoldi was born in London UK. His Father was Domeneck Grimoldi, who was born in Amsterdam with an Italian Father and Dutch mother. Domeneck was also a scientific instrument maker. John B Grimoldi had served his apprenticeship to his older brother Henry Grimoldi in Brooke Street, Holburn, London and had emigrated from England to Australia to start his own meteorological and scientific instrument makers business at 81 Queens St Melbourne. He operated his business in 1862 until 1883 when it was brought by William Samuel and Charles Frederick, also well known scientific instrument makers who had emigrated to Melbourne in 1875. John Grimoldi became successful and made a number of high quality measuring instruments for the Meteorological Observatory in Melbourne. The barometer was installed at Warrnambool's old jetty and then the Breakwater as part of the Victorian Government's insistence that barometers be placed at all major Victorian ports. This coastal barometer is representative of barometers that were installed through this government scheme that began in 1866. The collecting of meteorological data was an important aspect of the Melbourne Observatory's work from its inception. Just as astronomy had an important practical role to play in navigation, timekeeping and surveying, so the meteorological service provided up to date weather information and forecasts that were essential for shipping and agriculture. As a result, instruments made by the early instrument makers of Australia was of significant importance to the development and safe trading of companies operating during the Victorian colonies early days. The provenance of this artefact is well documented and demonstrates, in particular, the importance of the barometer to the local fishermen and mariners of Warrnambool. This barometer is historically significant for its association with Langlands’ Foundry which pioneered technology in the developing colony by establishing the first ironworks in Melbourne founded in 1842. Also, it is significant for its connection to John B Grimoldi who made the barometer and thermometer housed in the cast iron case. Grimoldi, a successful meteorological and scientific instrument maker, arrived in the colony from England and established his business in 1862 becoming an instrument maker to the Melbourne Observatory. Additional significance is its completeness and for its rarity, as it is believed to be one of only two extant barometers of this type and in 1986 it was moved to Flagstaff Hill Maritime Village as part of its museum collection. Coast Barometer No. 8 is a tall, red painted cast iron pillar containing a vertical combined barometer and thermometer. Half way down in the cast iron framed glass door is a keyhole. Inside is a wooden case containing a mercury barometer at the top with a thermometer attached underneath, each with a separate glass window and a silver coloured metal backing plate. Just below the barometer, on the right-hand side, is a brass disc with a hole for a gauge key in the centre. The barometer has a silvered tin backing plate with a scale, in inches, of "27 to 31" on the right side and includes a Vernier with finer markings, which is set by turning the gauge key. The thermometer has a silvered tin backing plate with a scale on the left side of "30 to 140". Each of the scales has markings showing the units between the numbers.Inscription at the top front of the pillar reads "COAST BAROMETER" Inscribed on the bottom of the pillar is "No 8". and "LANGLANDS BROS & CO ENGINEERS MELBOURNE " The barometer backing plate is inscribed "COAST BAROMETER NO. 8, VICTORIA" and printed on the left of the scale, has "J GRIMOLDI" on the top and left of the scale, inscribed "Maker, MELBOURNE". There is an inscription on the bottom right-hand side of the thermometer scale, just above the 30 mark "FREEZING" Etched into the timber inside the case are the Roman numerals "VIII" (the number 8)flagstaff hill, warrnambool, maritime village, maritime museum, flagstaff hill maritime museum & village, shipwreck coast, great ocean road, warrnambool breakwater, coast barometer, coastal barometer, barometer, weather warning, ports and harbours, fishery barometer, sea coast barometer, austral otis co, coast barometer no. 8, henry grimoldi, henry langlands, john baptist grimoldi, langlands foundry co, meteorological instrument maker, robert langlands, scientific instrument maker, thermometer, thomas fulton -

Octant, Late 18th to mid-19th century
... instrument maker... Coutinho. Henry Hemsley was a lesser-known instrument maker... was a lesser-known instrument maker and optician working in London ...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.

Instrument - Hydrometer, J Long (Joseph Long), late 19th - early 20th century
... Loftus of London instrument maker... Loftus of London instrument maker Loftus J Long Sikes Hydrometer ...This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base. The case has ten vertical pegs to secure the weights. The brass hydrometer has a spherical float and eight thick brass horseshoe-shaped weights. The serial number is on each section of the float and all weights. Both sides of the float’s upper flat stem have a scale from 0-10, with five divisions between each number. The eight weights are numbered from 20 – 90 in increments of 10. The set includes a mercury thermometer mounted on an ivory back plate labelled with Fahrenheit and Centigrade Scales. The Sikes hydrometer set was made by Loftus of London. The hydrometer model is IID 510, Serial Number is 14674, calibrated by Longs, London. All parts of the float and eight weights are inscribed with Serial Number “14674” The float stem is stamped "SIKE'S IID 51o” Calibrator, "LONG LITTLE TOWER ST LONDON" The weights are numbered individually ”20”, “30”, “40”, “50”, “60”, “70”, “80” or “90” Each weight in inscribed; symbol “(J L) [inside an ova, with textured background]” The thermometer inscribed: “LOFTUS OF LONDON”flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, measuring instruments, customs tax, weighing instrument, sike’s hydrometer, calibrator long of london, loftus of london instrument maker, loftus, j long, sikes hydrometer, scientific instrument, pressure measurement, measuring instrument, ullage tool, customs, excise duty, tax, alcohol content, proof, calibrate, standard weights and measures, tariff, scientific instrument makers, specific gravity, liquid density, alcohol testing, technology, alcohol measurement, proof spirit, wine and spirits merchants, local business, brass measuring instrument, port fairy, customs office, port fairy customs, joseph long, instrument maker -

Instrument - Telescope, Early 18th Century
... instrument maker... instrument maker James Short invents the first parabolic and elliptic... instrument maker James Short invents the first parabolic and elliptic ...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.

Inclinometer has "JOHN LILLEY ...Mr John Wilson Gillie was born on the 31st of March 1864. On the 31st of July 1880 he was apprenticed for four years to J.J. Wilson and Sons, Nautical Instrument Makers of Sunderland. Following the apprenticeship he spent six months to a year as an ‘improver’ in Glasgow, and then started a new company ‘Wilson and Gillie’ in North Shields. At this time sail had just given way to steam and wooden ships to steel, and the railways were competing with colliers for the carrying of coal from the North East of England to London and the South. In 1858 only seven out of 44 shipyards on the Tyne were using iron, but by 1862 there were ten, employing around 4,000 men. These changes had a significant effect on nautical instrument manufacturers, as the magnetic compass for a wooden sailing vessel was very simple and required little in the way of compensation. For steel vessels much more was required and this was a period of great development, both in the compass bowl and the binnacle in which it was housed. In 1870 Sir William Thomson (later Lord Kelvin) designed his dry card standard compass, which completely replaced all previous designs. Wilson and Gillie started as agents for the Thomson compass, but later J.W. Gillie, using similar principles, redesigned the compass suspension and patented the ‘UNIT’ standard compass. It became popular with local shipowners and shipbuilders. In 1910 the firm of John Lilley and Son (which had been established in London in 1812), found themselves in financial difficulties and were saved with the help of John Wilson Gillie, who established, on the 8th of August 1911, a new firm of John Lilley and Son Limited. John Lilley and Son had been the sole London agents for Sir William Thomson, a very enviable position during this period, when the Thomson compass led the field. Unfortunately, Mr. Lilley had quarreled with the Glasgow company, who withdrew the agency and established their own branch in London (later to become Kelvin White and Hutton). On November 7th 1913, the firm of John Lilley and Son Limited of London amalgamated with Wilson and Gillie of North Shields, and after this date instruments manufactured by the two companies bore the name John Lilley and Son Limited of London and North Shields. During the 1930s many of the London nautical instrument makers were in difficulties, including John Lilley and Son Limited and Reynolds and Son, Dobbie and Clyde Limited, and Mr. J.W. Gillie arranged an amalgamation between these two companies. The new firm became Lilley and Reynolds Limited. In 1943, with estate duties in mind, the North Shields company was reconstituted and took the name of John Lilley and Gillie Limited, although the shareholders, directors and personnel remained unchanged In the early 1970s Lilley and Gillie developed close links with Observator in Rotterdam, who manufactured one of the first fully reliable transmitting magnetic compass systems. The Observator shareholders, Holland America Line, bought the share capital of John Lilley and Gillie Limited., but retained all the personnel and the directors. (See Links for more information)A significant item of early 20th century marine navigational equipment made by a leading manufacturer in the field from a company that is still producing marine navigational instruments today. John Lilleys company began in 1812 growing at a time when the transition of compasses from timber ships, to steel vessels. Compasses at this time required a method of compensation to allow their inclusion in steel vessels without magnetic deviation. This therefore was a period of great development, both in the compass bowl and the binnacle in which it was housed and the Lilley company were leaders in the field. Ships binnacle, wood with brass fittings, consists of 2 brass lamp holders, place for compass, Also has an inclinometer with a scale 40 to 0 to 40, one red and one green iron Kelvin compensation balls, one on each side of binnacle denoting port and starboard, a brass cylinder attached perpendicular at the rear for storing a Flinders Bar, 2 hinged cupboards containing adjustable wooden racks with drilled holes in them to hold iron Heeling error magnets.Textured brass plate attached to front stating "JOHN LILLEY & SON LTD (WILSON & GILLIE), NAUTICAL INSTRUMENT MAKERS, NORTH SHIELDS" .

... makers and mathematical instrument makers based in London... optical instrument makers and mathematical instrument makers based ...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.

The company made compasses for aircraft notably, Spitfires, Tiger moths and Concord. Henry Browne was born in Lewis, Sussex in 1842 and died in Barking in 1935. His company was a well respected English instrument maker that had been making and selling fine quality compasses, ship's clocks, inclinometers, sextants, and chandlery items for over 140 years. It started in a factory in Brightlingsea, Essex and moved to Barking in 1929. The Trade Mark brand Sestrel was used on all their equipment. Their “Dead Beat“ compass design is well dampened serving to reduce oscillations. It is reported that this design compass was fitted to many Allied ships during WW II. The company went through a boom period in the 1970s but collapsed in the 1980s due to the popularity of cheaper plastic compasses over tradition brass ones. Over more recent years, there has been a consolidation of British instrument makers and the firm of Henry Browne & Son has changed hands a number of times. At last count, it became part of Lillie & Gillie of London in 1985 when John Lilley & Gillie Ltd acquires the assets of Henry Browne & Sons (Sestrel) Ltd, a major competitor for what may be the second time. The model name of Sestral came about via the following.Take first two letters of the word Sensitive then the firs two letter of steady and the firs three letters of reliable hence the trade name of "Sestral".

Hechelmann” a marine instrument maker of which Gehna is an acronym ...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.

... for which he undertook he was also an accredited instrument maker,he... he was also an accredited instrument maker,he clearly ...James Henry Steward (1817–1896) established J.H. Steward in London in 1852. As “Head Optician” he would have been a qualified oculist but little is known about the founder’s early life and scholastic achievements. However, given the variety of disciplines for which he undertook he was also an accredited instrument maker,he clearly was a gifted scholar and quickly gained professional recognition in a full range of fields for an instrument maker of his day. J.H Steward became incorporated as J.H. Steward Limited on 1st February,1913. The business grew from modest beginnings. Steward would sell pocket watches and assorted items at the annual competition days of "The National Rifle Association of the United Kingdom(NRA)" from a stall. As the governing body for full bore rifle and pistol shooting sports in the UK. The Association established in 1859 with the aim to improve the shooting skills of the newly formed corps of volunteers to meet the perceived threat of an invasion by the French. J.H. Steward advert first appeared in the NRA competition program of 1865. The NRA meetings were held at first on Wimbledon Common, Surrey until 1889. Then because of pressure by the local community, the NRA along with its buildings and its flourishing meetings moved further south to Brookwood, Surrey. By now the Steward operation had grown from a modest stall into a large marquee selling various optical and scientific instruments at these meetings. Throughout its long trading history the J.H. Steward company and many members of the family maintained strong ties to the NRA and competition shooting events. The NRA records show that at the end of the 19th century the NRA bestowed a Life Membership on 7 Steward family members. First presented by J. H. Steward Ltd. in 1902 was the “Steward Trophy” that is still an annual competition for teams of four from any rifle club affiliated to the NRA. There is also evidence that many family members were fine shots.The item was made by a significant instrument manufacturing company that concentrated during the middle 19th century on supplying the British military. This items pattern & design is still available as a reproduction, available on the internet. However this original seems unique as the writer cannot find another for sale or in a collection to date. The assumption is that this type of compass was made for the British artillery units given the sun dial.
