The Volunteer Air Observers Corps was an Australian air defence organisation of World War II.It was formed on 31 December 1941 to support the Royal Australian Air Force by sighting and observing aircraft over Australia.It swiftly established observation posts across Australia and provided information to the RAAF's regional air control posts. As the threat to Australia declined its role was expanded to include coast watching, assisting air traffic control and weather reporting. The corps was staffed by civilian volunteers and reached a peak strength of 24,000 personnel and 2,656 observation posts in 1944. After the end of the war the VAOC was reduced to a cadre in December 1945 and was disbanded on 10 April 1946. The Volunteer Air Observers Corps was an Australian air defence organisation of World War II. This certificate is a record of the participation of members of the Orbost district. Anita Armistead, wife of Francis Armistead had a son, Sydney, who served as a gunner in Malaysia during WW11.A certificate of service awarded to Mrs F.

In 1913, Mark Cowley Lidwill designed a machine for the purpose of mechanical or insufflation anaesthesia. The Lidwill machine was a portable machine weighing 7kg that could easily be packed into two small bags. The machine involved compressed air being delivered to an ether vaporiser. An ether/air control device allowed varying concentrations of ether to be delivered. The ether vaporiser could be immersed in hot water to prevent cooling and the ether temperature was measured. From the vaporiser, the ether/air mixture went through a trap bottle, then to a crude mercury blow-off valve and subsequently to the patient.Large leather suitcase style bag divided into two levels containing and insufflation anaesthesia machine.insufflation, mark cowley lidwill, thoracic surgery, positive pressure

David Robson has had a lifelong association with aircraft. He started flying at the age of 16 and served for 21 years in the RAAF as a fighter pilot, test pilot and forward air controller (including a tour in Vietnam in the 0-2A). His hobby is painting, and he naturally turns to his own experiences and visual images to convey the wonders and beauty of flight, the camaraderie of the Services and ugliness of war.Original watercolour of USAF Cessna 0-2A supporting A/An Army Bell Helicopter in 1969 in Phuoc Tuy Province. Call sings Jade and Possum respectively. The scene portrayed in the watercolour is of a USAF Cessna 0-2A aircraft supporting an Australian Army Bell 47 helicopter in 1969. the team operated in Phuoc Tuy Province in support of the 1st australian Task Force. the 0-2A was a Forward Air Control aircraft flown by both USAF and RAAF pilips in this role. Jade 07 was the callsign reserved for a RAAF fighter pilot. As well as directing airstrikes in the Jad FAC gave top cover and navigational assistance to the Possum helicopter and , in return, the Possum provided very accurate BDA (Bomb Damage Assesment) following the airstrike.Signed by Artist David Robson 2001. cessna 0-2a, painting, phuoc tuy, david robson

The aircraft KYEEMA, a Douglas DC-2, crashed into the western face of Mt Dandenong in thick cloud on 25th October 1938. All 18 occupants on board were killed. The aircraft overshot Essendon Airport by 20 miles. The subsequent findings triggered the beginning of air traffic control and the establishment of the Department of Civil Aviation. This photograph was taken in 1938 by First Constable Carl Tepper of Russell Street Police Station. Carl Tepper was a cousin of Frank Child, grandson of Ted Child. They were related through the Dorey family.Sepia photograph showing the wreckage of an aeroplane spread in the forest amongst trees.

This is a set of four photographs of WO2 Graham Ragless from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988. The photos were probably taken at the School of Military Survey (SMS), Bonegilla, VIC. Texas Instruments TI4100 portable Global Positioning System (GPS) geodetic receivers were introduced from 1986–1988. The GPS receivers and Ferranti FILS3 helicopter and vehicle mounted Inertial Positioning System (IPS) replaced the TRANSIT satellite receivers. The equipment was deployed to establish the baseline for a GPS controlled air camera and photogrammetric system to significantly reduce the requirement for ground survey to accurately control air photography for topographic mapping. Personnel from the four field survey squadrons at this time were trained at the SMS to operate the TI4100 receivers. Field survey operations using GPS and IPS equipment followed in the late 1980s. This technology is described in more detail in the RA Svy booklet titled An Introduction to Topographic Mapping. See record ID - 6010. WO2 Graham Ragless progressed to the rank of WO1 and was appointed as RSM of the Army Survey Regiment from 1990 to 1992.

Japanese style box bellows (fukisashi/吹差鞴) reached their current and finalized form by about the sixth century. They are constructed almost entirely of wood and allow a smith to supply a highly controlled air blast to the forge by pulling and pushing the handle slowly back and forth. Using dual chambers and two sets of valves, the air is supplied on both the push and the pull stroke, and the blast may be highly intensified or stopped in an instant as needed by the smith.(http://islandblacksmith.ca/2015/06/why-you-need-a-swordsmiths-fuigo-box-bellows/, accessed 18 February 2018)Timber box with handle on the side which pulls out.fuigo bellows, japanese, bellows, fukisashi bellows, oriental box bellows, pump

In July 1947, the Commonwealth Defence Council approved the formation of a Fleet Air Arm which would be controlled and operated by the RAN. The initial planning included purchase of two aircraft carriers, aircraft and establishment of shore facilities. The carriers were named HMA Ships Sydney and Melbourne, and the shore facilities were at Nowra. HMAS Albatross was commissioned in August 1948 and the 20th Carrier Air Group, comprising Sea Fury and Firefly aircraft, was brought from England to Australia by HMAS Sydney. These aircraft, operated by 805 and 816 Squadrons, disembarked to Nowra in May 1949. In November 1950, they were joined by the Carrier Air Group of 808 and 817 Squadrons, also flying Sea Furies and Fireflies. HMAS Albatross has been expanding ever since. As more capable aircraft have been acquired, so ground support facilities have had to be built. In 1955, Sea Venoms and Gannets arrived, requiring radar workshops and test facilities. More aircraft necessitated stricter standards of air traffic control and a new control tower was built in 1958. In 1964 the introduction of Wessex helicopters, with a dunking sonar capability, required a further expansion of services. In 1965, it was decided to buy American aircraft to replace the ageing British Gannets and Sea Venoms. McDonnell Douglas Skyhawks and Grumman Trackers were chosenand additional avionics facilities were built to service the complex equipment they carried. The helicopters now based at HMAS Albatross have restored to the RAN much of the anti-submarine capability lost when the Tracker squadron was disbanded in 1983. In recent years significant redevelopment has taken place, continuing the operation of HMAS Albatross and recognising its strategic importance as the sole Royal Australian Navy Air Station.Wooden Plaque 15cm x 13cm with insignia of H.M.A.S.

“Sundial 2hp engine, open crank, 600rpm, serial number 6420.” These small 4 stroke engines were widely used on Australian farms through the 20th century to power chaffcutters, grinders, saws, lighting plants, pumps, shearing plants, milking machines and cream separators easing much of the drudgery of farm work. They were also used in garages and workshops and by bush fire brigades. The engine was made by H.V.McKay Massey Harris. At one time Hugh Victor McKay’s Sunshine Harvester Works was the largest factory in Australia but in 1930, to ensure survival during the Great Depression, elected to merge with the Australian arm of a Canadian firm, Massey Harris. The Sundial is fitted with twin flywheels, making it a compact and convenient power source as either wheel could double as a drive wheel. Its connecting rod, crankshaft and flywheel spokes are covered, a safety measure that was not standard at the time. These engines were advertised as simple, dependable, low in price and cheap to run. They had the additional advantage that a bolt-on kit was made by the manufacturer to convert them to run on kerosene. ‘The engine's output is two horsepower (1.5 kW) at 600 rpm. The compression ratio is 5:1 and the spark plug is activated by a high tension magneto. The fuel tank holds 3.3 litres and the cooling water hopper holds 6.6 litres. Cylinder bore is 101 mm and piston stroke is 115 mm.’ In a catalogue of HV McKay Massey Harris agricultural machinery published in March 1942, the engine is described as follows: 'The cylinder head is of the hot, turbulent type, giving the finest fuel atomisation and heat distribution. The carburettor, of special design, has an automatic air valve controlling the amount of air. The supersensitive, high speed, flyball-type governor provides an ample range of speed.'Typical of units used on local farms.

One of a few service vehicles built from almost new by the MMTB rather than being a converted vehicle. Donated to the BTM in 1999 and has been an operational tram 2001.Single truck (4 wheels), special purpose tram fitted with two cabs, control equipment, air brakes, track scrubber or cleaning equipment, pump, water and air lines to clean track. Carries approx. 4 cubic metres of water. The tram was built by the Melbourne and Metropolitan Tramways Board in 1934 using the cabs from a C class tram (No. 32). It was transported to the isolated Footscray system a number of times to clean the rails there. In 1961 it received additional body bracing and repainted in the diagonal black and string (light cream) stripes. The tram became 8W during 1975 as the then new Z class trams came into service. By the early 1990's the need for the tram and the other similar cars used to "scrub" the surface of the rails was no longer. The tram was stored at Malvern depot for many years before being donated to the Ballarat Tramway Museum by the Public Transport Commission in September 1999. It has been scrubbing the rails in Ballarat since March 2001. For a detailed article see April 2008 issue of Fares Please.

This compressor was part of the E.G. Ward Collection. It is connected to the diving suit and boots also in our collection. Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a German-born British engineer chiefly known for his contributions to diving equipment. Siebe Gorman traded as an engineering firm for over 180 years from 1819 to 1999. The early success of the business was due to its founder, the Prussian immigrant Christian 'Augustus' Siebe (1788-1872). For business reasons, he applied for and was granted British citizenship in 1856. He was a gifted engineer who was able to translate theoretical problems into practical, working products. During the industrial Victorian period, the business traded as 'A. Siebe' at 145 High Street Holborn London, but in 1828 new premises were acquired at 5 Denmark Street, Soho. The family firm produced a wide range of manufactured goods including paper-making machinery, measuring machinery, water-pumps, refrigeration equipment and diving apparatus. Augustus Siebe specialised in submarine engineering early on and the company gained a reputation for the manufacture of safe, reliable diving apparatus. Augustus Siebe is best remembered for the development and manufacture of the ‘closed’ Diving Dress based on the ideas of Charles and John Deane, George Edwards and Charles Pasley. Apart from some small modifications to valves and diver communications, the basic 12 bolt ‘closed’ diving dress remained relatively unchanged after the 1870s. Later company successes were also based on innovation, with new products that could be successfully developed and manufactured to high standards. This was largely attributed to the inventive nature, foresight, engineering and entrepreneurial skills of Robert Henry Davis (1870-1965). In 1882, RH Davis joined the company of 'Siebe & Gorman' as a young 11-year-old office boy and he was to remain with the company until he died in 1965. Augustus Siebe retired in 1869 and handed over the company to a new partnership of Henry H. Siebe (1830-1885) and William A. O'Gorman (1834-1904). The new firm traded as 'Siebe & Gorman' (1870-1879) from premises in and around Mason Street, Westminster Bridge Road, Lambeth, London. The two partners soon recognised the potential of R.H. Davis and in 1894, aged 24, he became General Manager of Siebe & Gorman. Davis increasingly ran the company until the surviving partner (W.A. Gorman) died in 1904. The firm was disposed of to the Vickers (armaments) family and a new company 'Siebe Gorman & Co. Ltd.' (1905-1998) was formed. Under the chairmanship of Albert Vickers, R.H. Davis was kept on as Managing Director, and the company forged ahead. However, after WW1, the Great Depression caused manufacturing output and share prices to slump. In 1924 Robert Davis made a deal with the Vickers Board and acquired control of the company through majority shares. Under his leadership, the Siebe Gorman Company flourished and within time, four of his sons also joined the firm. The company gained a worldwide reputation for the manufacture of diving apparatus, decompression and observation chambers, and safety breathing apparatus of all types for use on the land, in the air and under the sea (including mine rescue, tunneling, aircraft, diving, submarine escape and in other hazardous environments). Close research and development links with the MOD (especially the Admiralty), also provided a lucrative outlet for the company products. In 1932, Robert Davis was knighted by King George V, principally for his invention of the ‘Davis Submerged Escape Apparatus’ (D.S.E.A.). Siebe Gorman essentially remained a family firm from the beginning (under A Siebe) until it became a public company for the first time in 1952. However, following WW2, British manufacturing stagnated through stifled investment and post-war austerity, and there was little innovation. Siebe Gorman fortunes began to decline as an ageing Sir Robert Davis failed to invest, or change the company business and management practices. In 1959, Siebe Gorman was acquired by the “Fairy Group” and the ailing Sir Robert was made Life President. Consequently, nothing changed and the slow decline continued until Sir Robert's death in March 1965. Around 1960, Siebe Gorman acquired the diving apparatus manufacturer C E Heinke, and for a brief period, it manufactured some diving equipment under the combined name of Siebe Heinke. Around 1964, Mr. E. 'Barry' Stephens was appointed as the new Managing Director to modernise Siebe Gorman. Changes were made, including a move to a new factory in Wales in 1975. The new company concentrated on fire fighting breathing apparatus and escape equipment, and the move coincided with the loss of many of the older, traditional craft skills. Between 1985 and 1998, Siebe expanded through acquisitions, and several other companies were acquired. The Siebe Gorman (diving apparatus) company has therefore traded as A. Siebe (1819-1870); Siebe & Gorman (1870-1879); Siebe Gorman & Co (1880-1904); Siebe Gorman & Co. Ltd (1905-1998).The compressor is a very significant item as it gives a snapshot into marine history and the development of diving equipment generally especially that used for salvage operations before and during WW2. Siebe & Gorman the company that made the equipment was a leading inventor, developer and innovator of marine equipment with its early helmets and other items eagerly sought after today for collections around the world. The items in the Flagstaff Hill collection give us an insight as to how divers operated and the dangers they faced doing a very necessary and dangerous job during the early days of marine exploration.A single cylinder divers' pump by Siebe Gorman & Co Ltd, London, eccentric hand cranked in brass mounted mahogany case with instructions to the underside of the lid, brass covered pressure gauge and air outlet, brass makers plaque to the front, water inlet and outlet to the rear, green painted lifting rings.

This is a set of 14 photographs of RA Svy technicians operating photogrammetric equipment in Air Survey Squadron, Army Survey Regiment, Fortuna, Bendigo; and the School of Military Survey Bonegilla c1960s to c1980s. The Wild B9 stereo plotter were introduced in 1962 and the Wild B8 stereo plotter was introduced in 1966. The Wild B9 and B8 stereo plotters were used for plotting topographic detail and contours. These analogue machines were manually controlled by adjusting the control knobs for the orientation of the 3D image. The B9s used a four and a half square, and the B8s used a nine-inch square photo image on a film or glass diapositive which allowed highly accurate extraction of map features. At first, plotting with B8 and B9 stereo plotters was undertaken at the aerial photography scale of 1:80,000 in pencil onto a controlled plotting sheet. Sheets were then inked up and reduced photographically to the 1: 100,000 publication scale for scribe impression production. In the early days topographic detail and contours were plotted with a pencil or ink pen mounted at the far end of the pantograph arm. The plotting procedure was upgraded to direct plotting in ink with photographic reduction to publication scale. In 1975 four B8s were upgraded with tri-axis locaters as part of the Input Sub-system to enable digital extraction to AUTOMAP 1’s topographic database. When AUTOMAP 2 was introduced in 1982 these B8s were upgraded, and additional machines added to expand the Army Survey Regiment’s digital capture capability. There are several more photos catalogued in the Victorian Collections database of RA Svy personnel operating Wild B9 and B8 stereo plotters.Photogrammetric Equipment – Army Survey Regiment, Fortuna, Bendigo c.1981. . .7) – Unidentified technician operating Wild B8 stereo plotter in AUTOMAP 1 at ASR. .8) - Wild B8 stereo plotter in AUTOMAP 1 at ASR.

Operation Instruction 8/75, Operation Sandy Bush Phase 3 was conducted in the period 1 Oct to 30 Nov 1975 by Det A, 8 Fd Svy Sqn. The Operation was to complete the marking, panelling measurement of already marked control in the Louisiade and D'Entrecasteaux groups and to Recce, Mark, Panel and Measure new survey control in the Trobriand and Woodlark Islands. In addition Photo Identification was to be obtained of all marked survey control. Panelling was the process of accurately laying out large sheets of white plastic to form a cross over the Survey Control Points (Points where the position is accurately known) so that they could then be photographed from the air. The positions of these crosses could then be accurately transferred from this new photography in stereo onto the aerial photography coverage used to produce mapping.Typed Instructions and diagrams without cover, 14 x A4 pages stapled in Top Left Hand Corner.Some annotations in top LH corner8 fd svy sqn, rasvy, royal australian survey corps, fortuna, army survey regiment, army svy regt

This is a set of eight photographs of technicians operating photogrammetric equipment in Air Survey Squadron, Army Survey Regiment, Fortuna, Bendigo. c1960s to c1980s. The Wild A9 Stereocomparator and Wild B9 stereo plotter were introduced in 1962. The Wild B8 stereo plotter was introduced in 1966. Technicians used the Wild A9 Stereocomparator to accurately measure between pass, tie, and survey control points on aerial photographs. The Wild B9 and B8s were used for plotting topographic detail and contours. These analogue machines were manually controlled by adjusting the control knobs for the orientation of the 3D image. The B9s used a four and a half square, and the B8s used a nine-inch square photo image on a film or glass diapositive which allowed highly accurate extraction of map features.
