Instrument - Thermometer, 20th century
Thermometer made to the specifications of Dr. Forbes. Used to measuring temperatures from freezing to boiling. It was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he would take time to further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . The organisation began in South Australia through the Presbyterian Church in that year, with its first station being in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill where he’d previously worked as Medical Assistant and purchased a share of the Nelson Street practice and Mira hospital from Dr Les Middleton one of the Middleton Brothers, the current owners of what was once Dr Tom Ryan’s practice. Dr L Middleton was House Surgeon to the Nhill Hospital 1926-1933, when he resigned. [Dr Tom Ryan’s practice had originally belonged to his older brother Dr Edward Ryan, who came to Nhill in 1885. Dr Edward saw patients at his rooms, firstly in Victoria Street and in 1886 in Nelson Street, until 1901. The Nelson Street practice also had a 2 bed ward, called Mira Private Hospital ). Dr Edward Ryan was House Surgeon at the Nhill Hospital 1884-1902 . He also had occasions where he successfully performed veterinary surgery for the local farmers too. Dr Tom Ryan then purchased the practice from his brother in 1901. Both Dr Edward and Dr Tom Ryan work as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He too was House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. Dr Tom Ryan moved from Nhill in 1926. He became a Fellow of the Royal Australasian College of Surgeons in 1927, soon after its formation, a rare accolade for a doctor outside any of the major cities. He remained a bachelor and died suddenly on 7th Dec 1955, aged 91, at his home in Ararat. Scholarships and prizes are still awarded to medical students in the honour of Dr T.F. Ryan and his father, Dr Michael Ryan, and brother, John Patrick Ryan. ] When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. His practitioner’s plate from his Nhill surgery states “HOURS Daily, except Tuesdays, Fridays and Saturday afternoons, 9-10am, 2-4pm, 7-8pm. Sundays by appointment”. This plate is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. Dr Edward Ryan and Dr Tom Ryan had an extensive collection of historical medical equipment and materials spanning 1884-1926 and when Dr Angus took up practice in their old premises he obtained this collection, a large part of which is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. During his time in Nhill Dr Angus was involved in the merging of the Mira Hospital and Nhill Public Hospital into one public hospital and the property titles passed on to Nhill Hospital in 1939. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. ). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (The duties of a Port Medical Officer were outlined by the Colonial Secretary on 21st June, 1839 under the terms of the Quarantine Act. Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served as a Surgeon Captain during WWII1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. Their interests included organisations such as Red Cross, Rostrum, Warrnambool and District Historical Society (founding members), Wine and Food Society, Steering Committee for Tertiary Education in Warrnambool, Local National Trust, Good Neighbour Council, Housing Commission Advisory Board, United Services Institute, Legion of Ex-Servicemen, Olympic Pool Committee, Food for Britain Organisation, Warrnambool Hospital, Anti-Cancer Council, Boys’ Club, Charitable Council, National Fitness Council and Air Raid Precautions Group. He was also a member of the Steam Preservation Society and derived much pleasure from a steam traction engine on his farm. He had an interest in people and the community He and his wife Gladys were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”. The W.R. Angus Collection is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being an historical example of medicine from late 19th to mid-20th century. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery. Thermometer, glass, part of the W.R. Angus Collection. Scale 15 - 240, "Dr Forbes Specifications."

Instrument - Spring Scale
The first spring balance in Britain was made around 1770 by Richard Salter of Bilston, near Wolverhampton. He and his nephews John & George, founded the firm of George Salter & Co., still notable makers of scales and balances, who in 1838 patented the spring balance. They also applied the same spring balance principle to steam locomotive safety valves, replacing the earlier deadweight valves. https://en.wikipedia.org/wiki/Spring_scale Today, spring scales are very popular with recreational fishers. The ability to weigh things reasonably accurately with a small inexpensive apparatus allowed for the exact weight of items to be ascertained. However, it was not accurate enough to weigh small amounts in ounces or grams.Scale. Has ring for hanging, spring and hook device for weighing.

Barrel Calipers, Early 20th Century
... instruments used to measure the strength of alcohol. These instruments... and other instruments used to measure the strength of alcohol ...The firm Dring and Fage were active from 1790 to 1940 in London and were manufacturers of hydrometers and mathematical instruments they became established in London in 1790 by John Dring, who was a brass worker and hydrometer maker, and William Fage. Dring and Fage manufactured also saccharometers and other instruments used to measure the strength of alcohol. These instruments were primarily used to calculate excises. They traded at various addresses in London and they were at 56 Stamford St. between 1903 and 1938. By 1850 the company was owned by Edward Hall and Edward Jenkin and in 1940 the company became Dring & Fage Ltd, trading till the 1960s.Historically, gauging has meant measuring a volume, these gauging instruments were used by Customs and Excise and manufacturers for determining the volume and contents of liquid containers. For Customs the determination and collection of duty on imported goods which has had a very long history. Chaucer was a Customs Officer as was his father and grandfather, excise was first officially introduced in 1643, with the aim of maintaining military forces raised by the English Parliament at that time. Excise was initially a duty on home produced alcoholic beverages and soap but being easily applied, spread rapidly to a wide range of goods including imports of varying kinds. The government departments of Customs and Excise merged only in 1909 and it is from around this time that our instrument was made and used. The item demonstrates a long social history of the practice of Government's collecting duty on alcoholic beverages and thereby makes this item historically significant as it was used locally at Port Fairy by the ports Customs agents.

Engine Dynamometer, c.1890’s
... , fitted oak case. This brass instrument is used to measure... instrument is used to measure and record steam pressure for setting ...The steam engine indicator, or dynamometer, is an instrument used on a steam engine (such as that of a vessel or train) to measure and record the change in the pressures of the engine’s cylinders during their operating cycle. The engineer would use it to identify problems or defects such as bad valve settings or constricted steam pipes. It could indicate the difference in efficiency caused by adjustments made to the engine, being able to instantly measure the variation of pressure from the engine stroke at any given time. This force of power would be registered by a pencil, fitted to the adjustable arm, which would trace a line on paper wound around the cylinder. The recorded information could be used in conjunction with mathematical tables. This particular instrument was made by T.S. Mc Innes, one of the better manufacturers of engine indicators. Mc Innes engine indicators were still being used in the mid 1900’s. This specific instrument was used by Mark Forsythe of North Berwial, Scotland and late of Ararat, Victoria when he was chief engineer on the “SS Talawena” in 1892. The Port of Warrnambool, in Victoria, harboured steam ships that carried both passengers and cargo along the south west coast in the late 1800’s and into the 1900’s. The engineer of a steam ship was responsible for reaching and maintaining the optimum level of steam energy to serve the locomotion and efficiency of the steam ship. The engineer would use a steam engine indicator to measure and record information to achieve this purpose. Engine Dynamometer or Steam Engine Indicator in square, fitted oak case. This brass instrument is used to measure and record steam pressure for setting up and adjusting valves on a steam engine. It has an oscillating recording drum with vertical, silver clip attached for holding paper in place around the drum. The drum oscillates left to right. There is a pulley attached to a length of cord, which is attached to the drum. Beside the drum is a fine metal arm, vertically adjustable, small hole in the end to hold a pencil. Inscription stamped into bracket of the arm. The engine indicator is mounted on a hinged side of the case that swings out ready for use. Attached chains prevent the side from opening past vertical. There is storage for other accessories and an empty compartment in the base (where a scale or ruler may have been located). The case has a collapsible wooden handle, brass hinges and two brass, hook-shaped catches. There is a code stamped inside the lid. It contains a brass, ‘T’ shaped steam-cock (or stop cock) with two open ends made of metal pipe with different sized threads. (Turning the handle on top opens and closes the space in the pipe and would close off the flow of steam from one end to the other.) Also inside the case are three different spiral springs, each with a threaded nut on the end that has a threaded hole inside it. Used by Mr Mark Forsythe when chief engineer on the SS Talawena in 1892 “T.S.

Instrument - Ship Log, 1880-1890
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.

Instrument - Scale, Computing Scale Company, 1897-1900
In 1885 Julius Pitrat of Gallipolis, Ohio, patented the first computing scale. Six years later, Edward Canby and Orange Ozias of Dayton, Ohio, purchased Pitrat's patents and incorporated The Computing Scale Company as the world's first computing scale vendor. And four years after that, The Computing Scale Company introduced the first automatic computing scale In 1911. the Computing Scale Company merged with the International Time Recording Company and Tabulating Machine Company to form the Computing-Tabulating-Recording Company, a business that was renamed IBM in 1924. An early example of a hanging clock face scale patented in October 1897 and made by a company that pioneered the first computing scales used in retail businesses. This company went on to become incorporated with IBM that late became an international computer manufacturer.Scale, patented Oct 12, 1897. Measures in pounds and ounces, up to 10lb.

Instrument - Ship Log, Early 20th Century
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.

Equipment - Standard measure, Mid to late 19th Century
The beginning of standardised weights and measures began In Victoria when the Melbourne Observatory received sets of standard weights and measures, which had been tested in Britain against the then British Imperial standards. These included the primary standard yard and pound for the Colony of Victoria. Other standards of weights and measure held by shires and the administrative body's within the colony could then be compared to these primary standards. A Weights and Measures Act was passed in Victoria in 1862, establishing local inspectors throughout the colony. By the 1870s each local council and shire in Victoria held a set of standards that were used to test scales, weights and dry measures used by wholesalers, factories and shops. Every ten years the councils’ standards would themselves need to be rechecked against the Victorian Standards. The checking was done by the Victorian Customs Department in the 19th century, but with the transfer of responsibility for customs to the Federal Government in 1901, weights and measures function was retained by the Victorian Government and was shifted to the Melbourne Observatory. In 1904, a new building was erected at the south end of the Great Melbourne Telescope House, where the standard weights and measures and testing equipment was installed. This room had a large whirling apparatus for testing air meters and became known as the Whirling Room. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue and this branch remained at the Observatory site unit until 1995. J & M Ewan History: J&M Ewan was a Melbourne firm that began by selling retail furniture and wholesale ironmongery. They had substantial warehouses situated at the intersection of 81-83 Elizabeth and Little Collins Streets, the business was established by James M Ewan in 1852. Shortly afterwards he went into partnership with William Kerr Thomson and Samuel Renwick. When Ewan died in 1868 his partners carried on and expanded the business under his name J & M Ewan. The business was expanded to provide a retail shop, counting-house and private offices. Wholesale warehouses adjoined these premises at 4, 6 and 10 Little Collins Street, West. This company provided and sold a large and varied amount of imported goods into the colony that consisted of agriculture equipment, building materials, mining items as well as steam engines, tools of all types and marble fireplaces.

Robert Bate History: Robert Brettell Bate (1782-1847) was born in Stourbridge, England, one of four sons of Overs Bate, a mercer (a dealer in textile fabrics, especially silks, velvet's, and other fine materials)and banker. Bate moved to London, and in 1813 was noticed for his scientific instrument making ability through the authority of the “Clockmakers Company”. Sometime in the year 1813 it was discovered that one Robert Brettell Bate, regarded as a foreigner in London had opened a premises in the Poultry selling area of London. He was a Mathematical Instrument maker selling sundials and other various instruments of the clock making. In 1824, Bate, in preparation for his work on standards and weights, leased larger premises at 20 and 21 Poultry, London, at a rental of four hundred pounds per annum. It was there that Bate produced quality metrological instruments, which afforded him the recognition as one of one of the finest and principal English metrological instrument-makers of the nineteenth century. English standards at this time were generally in a muddle, with local standards varying from shire to shire. On 17 June 1824, an Act of Parliament was passed making a universal range of weights, measures, and lengths for the United Kingdom, and Bate was given the job of crafting many of the metrological artifacts. He was under instruction from the renown physicist Henry Kater F.R.S. (1777-1835) to make standards and to have them deposited in the principal cities throughout the United Kingdom and colonies. Bate experimented with tin-copper alloys to find the best combination for these items and by October 1824, he had provided Kater with prototypes to test troy and avoirdupois pounds, and samples with which to divide the troy into grams. Bate also cast the standard for the bushel, and by February 1825, had provided all the standards required of him by the Exchequer, Guildhalls of Edinburgh, and Dublin. In 1824, he also made a troy pound standard weight for the United States, which was certified for its accuracy by Kater and deposited with the US Mint in 1827. Kater, in his address to the Royal Society of London, acknowledged Bate's outstanding experimentation and craftsmanship in producing standards of weights, measures, and lengths.

Equipment - Standard measure, Mid to Late 19th Century
The beginning of standardised weights and measures began In Victoria when the Melbourne Observatory received sets of standard weights and measures, which had been tested in Britain against the then British Imperial standards. These included the primary standard yard and pound for the Colony of Victoria. Other standards of weights and measure held by shires and the administrative body's within the colony could then be compared to these primary standards. A Weights and Measures Act was passed in Victoria in 1862, establishing local inspectors throughout the colony. By the 1870s each local council and shire in Victoria held a set of standards that were used to test scales, weights and dry measures used by wholesalers, factories and shops. Every ten years the councils’ standards would themselves need to be rechecked against the Victorian Standards. The checking was done by the Victorian Customs Department in the 19th century, but with the transfer of responsibility for customs to the Federal Government in 1901, weights and measures function was retained by the Victorian Government and was shifted to the Melbourne Observatory. In 1904, a new building was erected at the south end of the Great Melbourne Telescope House, where the standard weights and measures and testing equipment was installed. This room had a large whirling apparatus for testing air meters and became known as the Whirling Room. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue and this branch remained at the Observatory site unit until 1995. J & M Ewan History: J&M Ewan was a Melbourne firm that began by selling retail furniture and wholesale ironmongery. They had substantial warehouses situated at the intersection of 81-83 Elizabeth and Little Collins Streets, the business was established by James M Ewan in 1852. Shortly afterwards he went into partnership with William Kerr Thomson and Samuel Renwick. When Ewan died in 1868 his partners carried on and expanded the business under his name J & M Ewan. The business was expanded to provide a retail shop, counting-house and private offices. Wholesale warehouses adjoined these premises at 4, 6 and 10 Little Collins Street, West. This company provided and sold a large and varied amount of imported goods into the colony that consisted of agriculture equipment, building materials, mining items as well as steam engines, tools of all types and marble fireplaces.

Scales Weighing Spring, mid to late 1900's
This type of mobile spring weighing scales were in high use before legislative Weights and Measure standards where in force throughout Australia. This was in a time when a "mans word and handshake" was his legal document. It was a time, especially in rural areas that the term "she'll be right" was extensively used and these types of scales (the accuracy over time) would produce a near "enough is good enough" measure. These scales are very significant for the rural produce within the Kiewa Valley. Rural produce such as hay milk and butter tubs,tobacco bundles could be easily weighed (in relatively smaller packages) for both markets and for use within the valley.This spring scale (!/2 Once to 4lb) was used as general weight scale. Because it is spring loaded the accuracy would fade over time and by over weighted loads. The spring enclosure is made from cast iron painter black. There is an iron ring at the top (attaching/holding) and an iron hook at the bottom (holding). There is a brass front plate with engraved markings(on the left side) running from top to bottom and a movable pin weight indicator running in the middle indicating the weight of the item being weighed.At the front top"SALTER'S SPRING BALANCE 4LB BY 21/2 OZ" underneath "No 1A" At the bottom in smaller print "MADE IN ENGLAND PATENT"weighing instruments, spring balances -

Meter Volt, mid to late 1900's
This analog voltmeter is quite a large (industrial type) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years. This voltmeter is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a small apparatus it was part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This analog volt meter has two metal rods protruding from the "back" of instrument with screw on points for the negative and the positive leads allowing the "current" to flow across the calibrated resistors to indicate on the "face" side the strength of the voltage "power". The "face" of the instrument has a zero point and then five evenly graduated marks from Zero to the "100, 200 and 300" marked points of measures. A large "V" below these pointers indicates that they represent levels of voltage. Three small screws hold the "face" in place. At the back of the meter is an aluminium "clasp" with three protruding screws (positioning fasteners) and a a screw tightening fixture for the correct fastening of the "clasp" into the correction location on the meter "board".Manufacturer's logo "CSG" underneath "ITALIA"kiewa valley tourism, victorian alps, alternate energy supplies, alpine population growth -

Meter Millivolt, after 1950
This milli-volt meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England.This milli-volt meter is very significant to the Kiewa Valley as it was used by those electrical technicians, who were part of the Kiewa Hydro Scheme. An "off spin" from the Scheme was the beginning of an explosion in "human" resources into the Kiewa Valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both industrial and larger residential community. This evolution in the Kiewa Valley created a change, not only in the "physical" landscape(better roads and infrastructure), but also the socio-economic growth within the Valley allowing other "tourist" based industries to expand within the valley and Alpine areas.This millivolts DC meter was used in the 1950's. It is contained in a wooden box and has two coloured (red/black, positive and negative) screw tight knobs which have bake-lite connections. It also has a covered (black tin) view meter marked from zero to 10 millivolts. Underneath this and within a round bake-lite is a small adjustment screw. The top of the box is fastened onto the main structure by six brass screws. The back of the structure is fastened by eight brass screws and there are four small bake-lite rest knobs.On the face of the millivolt compartment , and at the top "TO BE USED WITH DIAL HORIZONTAL TEMP.

Photograph - Johnson Ground Elevation Meter (JGEM) Survey Vehicle - Army Survey Regiment, Fortuna, Bendigo, c1960s
This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

Many Orbost babies were weighed on scales using these weights. Used in early 1930's.The early 20th century saw an emphasis in Australia on the reforming of mothering practices. There was a desire to improve infant mortality rates and produce healthy, well-adjusted citizens.Government organisations, in particular hospitals and baby clinics. encouraged mothers to measure their babies and regulate their feeding patterns. By the 1930s most mothers had been influenced to a greater or less extent by these new approaches to infant care. These weights are representative of that period.Two steel circular 10lb weights used with 106.1 scales used to weigh babies at Orbost Hospital.

Prisoptometer, Geneva Optical Company, Dr Culbertson's Prisoptometer, 1886 (estimated); late 19th century
How widely the prisoptometer was used is unclear but the Standard Optical Company later patented a new model, The Standard Prisoptometer, on June 21, 1904. Edward Jackson's crossed cylinder technique of determining astigmatism was first detailed in the Transactions of the American Ophthalmological Society (1887)4:595-598. The convenience of Jackson's crossed cylinder lenses over the prisoptometer in weight, cost, portability and reliability meant that they were soon almost universally adopted.This is a rare item as few are known world wide.This instrument is an optometer, that is, a device to measure the refractive error of an eye. It is made of cast iron, steel, brass and glass. It contains a prism which could be rotated, and was used to view a disc or an object circle. The prism caused monocular doubling of the object circle and the separation of the two images varied as the prism rotated, depending on the astigmatism present. The axis of the astigmatism was indicated by the prisoptometer and trial lenses were used to determine the the magnitude of the spherical and cylindrical refractive errorImprinted:"DR CULBERTSON'S PRISOPTOMETER/ GENEVA OPTICAL COMPANY MAKERS, GENEVA, N.Y./ PATENTED SEPT, 21, 1886".
