The theodolite was sold 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. (See further details below.) History for Troughton & Simms: Edward Troughton & William Simms established a scientific instrument making business in London in 1826. Edward Troughton (1756-1835) had previously had his own scientific instrument business, inherited from his father. His achievement's included a transit telescope for Greenwich Observatory (1816) and the precision surveying instruments for the Ordnance Survey of Britain, Ireland and India. William Simms (1793-1860) had trained as a goldsmith and began to gain work dividing circles on fine astronomical instruments. When William Simms died in 1860, the business was taken over by his son James and nephew William. Troughton & Simms shop in Fleet Street became the hub of the finest scientific instrument made in London, in a period in which there was an expanding demand for precision instruments, for astronomy, surveying and precision measurement. They made instruments for Greenwich Observatory, for imperial surveys and exploring expeditions. When fire destroyed the Houses of Parliament in 1834, the firm was commissioned to create new standard lengths, this required 10 years of testing against the remaining old measurements. Troughton and Simms made several of the main instruments for Melbourne Observatory, including an 18 inch azimuth used of the Geodetic Survey, portable transit instrument (circa 1850), zenith sector (1860), a 4.5 inch equatorial telescope (1862), an 8 inch equatorial telescope (1874) spectroscope (1877) and an 8 inch transit instrument in (1884). While the firm had an excellent reputation for quality the company exasperated many of its customers with delays of years in delivering some instruments. History for Thomas Gaunt: Thomas Ambrose Gaunt (1829 – 1890) was a jeweller, clock maker, and manufacturer of scientific instruments, whose head office and showroom were at 337–339 Bourke Street, Melbourne, Victoria, Australia. Thomas Gaunt established Melbourne's leading watchmaking, optical and jewellery business during the second half of the 19th century. Gaunt arrived in Melbourne in 1852, and by 1858 had established his own business at 14 Little Bourke Street. Around 1869 he moved to new premises in Bourke Street on the corner of Royal Arcade, Gaunt's shop quickly became a Melbourne institution. Gaunt proudly advertised that he was 'The only watch manufacturer in the Australian colonies'. While many watches and clocks may have had Gaunt's name on the dial, few would have been made locally. Gaunt did make some watches for exhibitions, and perhaps a few expensive watches for wealthy individuals. Gaunt's received a telegraph signal from Melbourne Observatory each day to correct his main clock and used this signal to rate and repair ship's chronometers and good quality watches. Thomas Gaunt also developed a department that focused on scientific instrumentation, making thermometers and barometers (from imported glass tubes), telescopes, surveying instruments and microscopes. Significance: With the rapid urban expansion, one of the most important needs of the new colony was to survey and map the landscape of the Australian Colony’s interior. Theodolites, such as this one, made by Troughton and Simms, who were significant scientific instrument makers of the 19th century were instrumental to the colony's surveyors and would have played an important part in their everyday work. This transit theodolite remains of national significance due to its pioneering role in Australian science and its association with Australia's earliest surveyors and astronomers. It is also significant for its association with nineteenth-century surveying instruments and instrument makers.

This clinometer, is a hand-held optical scientific instrument used in surveying to measure vertical angles. It is used to measure the angle of elevation from the ground in a right-angled triangle. It may have been used by a surveyor or a forester to measure the height of tall things where you couldn't possibly reach to the top of e.g. flag poles, buildings or trees.This item is an example of an early hand held measuring instrument.. Today the use of electronic sensors is an important component in the design and function of the clinometers.A rectangular wooden folding measuring instrument. the panels are brass framed.

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. It was made by London scientific instrument maker Troughton and Simms, which originated in 1826 and continued until 1922.Sextant and its fitted square wooden box.

Theodolites have been used to measure horizontal and vertical angles by surveyors since the 1500s. A theodolite is a precision instrument for measuring angles in the horizontal and vertical planes. Theodolites are used mainly for surveying applications, and have been adapted for specialized purposes in fields like meteorology and rocket launch technology. Theodolites, such as this one, were instrumental to early surveyors, and would have played a significant part in their everyday work. The plumb bob was used to set the instrument exactly over a fixed survey marker.This theodolite was made by Troughton and Simms, who were significant scientific instrument makers of the 19th century and early 20th century. In 1782 John Troughton purchased Benjamin Cole's shop in Fleet Street, London enabling him to sell his own signed products. His instrument making business supported several dynasties of Troughtons before becoming Troughton and Simms and later still Cooke Troughton & Simms. This firm was one of the most well respected firms of instrument makers of the 1800s. A grey metal theodolite - probably made of brass.

Theodolites are a highly accurate instrument that measures angles between designated visible points in the horizontal and vertical planes. The theodolite has a long history, with the term first found in 1571 in a surveying textbook 'A geometric practice named Pantometria' by Leonard Digges. (source https://en.wikipedia.org/wiki/Theodolite). Cooke Troughton & Simms began when John Troughton starting selling products in Fleet Street, London in 1782. He went into partnership with his brother Edward in 1807 who expanded the business considerably. William Simms, a former apprentice with the company was taken as a partner and then manager after Edward died in 1835 and the company became Troughton & Simms. By 1887 the company was able to produce all the parts necessary for their instruments and the company employed nearly 200 people and was one of the most well respected firms of instrument makers of the 1800's. James Simms, son of William who had inherited the company died in 1915 and the company was turned into a limited liability company by his two sons William and James. Things however were not so easy for the two sons and in 1922 the business was brought out by their rival T. Cooke & Sons becoming Cooke, Troughton & Simms. Theodolites are used by surveyors as part of their everyday work and although there is no specific information regarding the provenance of this particular one it is assumed it was used locally by the City of Bendigo and / or the Lands Department.A grey theodolite no 39161 made by Cooke, Thoughton & Simms.

This theodolite was used by `Mr Dawson' (presumably William Tennant Dawson c.1820-1873) who `surveyed much of the area around and beyond Stratford'. It was damaged by the fire which burnt the original Roseneath home in 1921, when the Macleods were in residence. (Mrs W.T. Dawson was a Macleod). One little boy aged 3 years was given the job of saving everything on the kitchen table when the fire started at breakfast time. The theodolite was possibly in use by Dawson when he laid out St Kilda Road.This theodoite consists of a bottom plate, which is damaged and has melted metal. This rises to a ball joint, on which is pivoted another plate on which were housed four screws, of which three remain, to adjust the level. Above this is another plate, with compass markings and melted glass."Troughton and Simm's/London" in fine engraving on upper plate.surveyors, instruments

A School of Military Survey Precis, 8 x foolscap sized pages of typed text, stapled and two hole punched. The precis No 3 covers the Observation procedure to be used for 1st, 2nd and 3rd Order Triangulation using the Royal Australian Survey Corps standard Cooke, Troughton and Simms Tavistock or Wild T2. The geodetic model Tavistock with a 5.25" horizontal circle should be used for 1st Order Triangulation and maybe used for 2nd Order Triangulation if specially directed. The standard Tavistock with 3.5" horizontal circle or the Wild T2 should be used for 2nd and 3rd Order observations. The Precis discusses the types of errors, the source of errors and the best ways of managing them. In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration.A School of Military Survey Precis, 8 x foolscap sized pages of typed text, stapled and two hole punched.royal australian survey corps, rasvy, fortuna, army survey regiment, army svy regt, asr, school of military survey, sms, balcombe
