Photograph, R. Preston, Down goods hauled by G42 about to depart Gellibrand, 14 December 1955
Drivers were highly skilled enginemen. Taking a train from Beech Forest to down to Gellibrand required the train to be controlled at 10 mph (16 km) without running out of air. When a brake application was made the brakes on the locomotive were applied harder than the train brakes. The brakes locked up and the engine would just slide along. Drivers used a retention valve on the loco, then released the loco brakes so as not to wear out the brake shoes. So the train pulled into Gellibrand ready to pull out again after refilling the loco with water.At Gellibrand, a Down goods train is about to depart the station on 14 December 1955. The train consists of the locomotive G42, a louvre van NO, two NQ wagons and a guard's or brake van NC. B/W.gellibrand; colac; beech forest; railway; -

Mr Joseph George of 26 Scheele Street Pictured as an Air Raid Precautions Officer during the 1939 – 1945 war. ARP officers controlled the areas around their homes to check on tell-tale lights showing in the ‘brownout’ conditions and advising on the black-out of homes. Street lights were dimmed and screened downwards and Joseph’s daughter Marie remembered sewing black Italian cloth curtains to hang over the windows. Joseph taught adult first aid classes in local schools, church halls and at The Surrey Dive. Joseph conducted his practical training sessions at the Quarry in Grovedale Road, in case they had to deal with an emergency in such a site. Joseph (Joe) and wife Emily Ruth were English migrants; they bought their home in Scheele Street in 1919. Daughter Marie was born in 1914 when they are listed in the electoral roll at 'Hasland', Croydon Road, Surrey Hills; his occupation is given as a boilermaker.

Instrument - Aircraft Control stick, Joy Stick presented to Pilot Officer Eric V. Read in 1937 after it was recovered from an aircraft he was flying had crashed in the Brisbane Ranges in December 1936
A Control Joy Stick presented to Pilot Officer Eric V. Read in 1937 after it was recovered from an aircraft he was flying had crashed in the Brisbane Ranges in December 1936. Eric Read was a 21 year old RAAF pilot who was on a flight over the Bacchus Marsh region to make meteorological observations. Read's plane came down in bad weather and crashed into a heavily wooded area of the Brisbane Ranges between Staughton Vale and Mount Wallace. An extensive air and ground search was conducted and after 32 hours Read was located, alive, but badly injured and unable to get out of the cockpit of the plane. He was first located from the air and then a rescue party was able to reach him through rough country and bring him to safety. Read recovered from his injuries and many years later gifted the control stick of the aircraft he had been flying as an item for the collection of the Bacchus Marsh and District Historical Society.This item is of local historical significance as an object related to a notable aircraft accident and subsequent rescue of the pilot. It is also significant for its rarity as a surviving piece of aviation equipment from this era.Control or Joy stick mounted on a wooden base.aircraft, aircraft accidents, eric v. read -

Photograph, The Cairn- Jimmy Melrose's plane crash site, 1988
Edna Barrie at the cairn, photo received from Graeme Minns in 1988. The cairn marks the site of Jimmy Melrose's plane crash in Melton South. The accident which happened on July 5th 1936. In 1934 Melrose made headlines with a series of spectacular flights. In July of that year, he set around Australia record and in that year established a new solo Australia England record when he flew to England to compete in the MacRoberston race with a De Havilland Puss Moth VH- YQO. The only Australian and the only solo pilot to complete the course within the time limit. He was seventh in finishing order and third in the handicap section making news again during the race with a dramatic landing in Darwin with empty fuel tanks. Late in 1935 Melrose imported the Phoenix for his “Adelaide to Anywhere” Charter Service. The previous year the Heston Aircraft Company had taken over the interests of the well known Comper Aircraft Company, and the first production of the new firm was the Phoenix, a single-engined all wooden five seater machine of sesquiplane configuration. The forward half of the fuselage was a streamlined rectangular section and the rear portion was a monocogue shell; the whole was of plywood fabric covered. The wing was built up of spruce box spars and lattice ribs, ply covered from the leading edge to the front spar and the fabric covered over the remainder. The tail surfaces were of similar construction. The most notable feature of the design was the lower stub wing which ran right across the fuselage embodying two box spars, plywood covered it housed the main undercarriage wheels when retracted and provided a substantial anchorage for the Nu form wing struts. The Dowty undercarriage retracted inwards, operated manually by hydraulic packs, Dual control fitted, with side by side seating for the pilots and three passenger seats behind. Power was a 200 h.p. De Havilland Gipsy VI 6 cylinder inverted in-line air-cooled engine. Six Phoenix were built; five of them registered in Great Britain and one of those was later sold abroad the remaining four were impressed into the R.A.F. in 1940. Specifications were: 40 feet 4 inches length 30 ft 2 ins height, 9ft 7ins, wing area 270 sq ft, Tare weight 2,600lbs loaded weight 3,300lbs; cruising speed 360 m.p.h. landing 50mph ceiling 14,000 ft range 700 miles. Melrose’s machine the first production aircraft was built early in 1936 and test flown of the 24th March. Painted green it carries the words “South Australian Centenary 1936” in silver of the fuselage and the name “Billing on the engine cowling in honor of Melrose’s uncle Noel Pemberton Billing, pioneer designer and founder of the Supermarine Aviation Company. The delivery flight was planned as a goodwill mission to publicise the forthcoming South Australian Centenary celebrations. Melrose left Dympne on the 9th April 1936, and flying via Marseilles, Naples, Athens, Baghdad, Basra, Karachi, Jodphur, Calcutta, Akyab, Penang, Singapore, Lombok, Darwin, Newcastle Waters and Alice Springs reached Adelaide on the 25th of April. Continuing the goodwill flight to other States, he visited Melbourne, Sydney, Newcastle, Grafton, Brisbane, Coff’s Harbour, Sydney again, Launceston, Hobart and Mount Gambier before returning to Adelaide on the 13th May. During June Jimmy made some charter flights and early in July was engaged by Mr. A.J. Campbell a director of several mining companies from Melbourne to Darwin to commence at Essendon on the4th July. However on that day low cloud and steady rain caused the postponement. There was little improvement and Melrose was advised to delay the departure again. However he wished to reach Oodnadatta that night, and when he observed the break in the clouds decided to leave. He planned to climb above the cloud and fly to Adelaide at 3,000 feet. The aircraft was airborne about 8.10 a.m. and was last seen from Essendon climbing above the clouds. At 8.45 people at Melton (30 miles West of Melbourne) heard an approaching aircraft. The engine noise increased abnormally and eye witnesses saw the machine fall out of control from the cloud base about 800 feet and then disintegrate, fragments were scattered for 1½ miles and both occupants were killed.

Photograph - Codling Collection 01 - Melba Theatre Wodonga and its Demolition, c1970s
Miss Olive Codling was a Foundation Member and a Life Member of the Wodonga Historical Society. Many of her prize-winning photos are held in the Society Collection. She also held a range of roles and committee positions in a wide range of Wodonga community organisations. MELBA THEATRE, WODONGA operated in the Shire Hall building on the corner of High Street and Melbourne Road (Elgin Street), Wodonga. The Shire Hall was built in 1890. The date on the facade of the building represents the date of the formation of the Shire in 1876. In December 1929, Enterprise Pictures were screening films in the open air theatre adjacent to the Shire Hall or sometimes in the hall itself. In 1943 “Melba Theatre, Shire Hall” was advertised with that name for the first time. In 1948 Mr K Bounader, a picture proprietor from Holbrook with 39 years in pictures behind him assumed control of the Melba Theatre, Wodonga. The Bounader family continued to run the theatre well into the 1960s. The hall was also used for functions such as school socials and concerts. Competition from drive-in theatres and television had an impact on theatre audiences. Finally, the Melba Theatre screened its last film in 1968. A school speech night in 1969 is the last known event in the Melba Theatre. It was demolished along with the Shire Hall in 1971 and replaced with a supermarket and car park.These images are significant as they document an historic buildings in Wodonga which played an important part in the social life of the community.2 black and white photos of the Melba Theatre in Wodonga and its demolition Over doorway: "MELBA THEATRE"high st wodonga, melba theatre, wodonga buildings -

Domestic object - Lantern - household
This is a typical example of a flat wick domestic paraffin lamp used in households prior to the introduction of electricity.A flat-wick lamp is a simple type of paraffin lamp, which burns paraffin drawn up through a wick by capillary action. A flat-wick lamp has a fuel tank (fount), with the lamp burner attached. Attached to the fuel tank, four prongs hold the glass chimney, which acts to prevent the flame from being blown out and enhances a thermally induced draft. The glass chimney needs a "throat", or slight constriction, to create the proper draft for complete combustion of the fuel; the draft carries more air (oxygen) past the flame, helping to produce a smokeless light, which is brighter than an open flame would produce. The wick holder has holes around the outer edges. When the lantern is lit and a chimney is attached, the thermally induced draft draws air through these holes and passes over the top of the wick. This has a cooling effect and keeps the wick from over heating. The lamp burner has a flat wick, made of cotton. The lower part of the wick dips into the fount and absorbs the paraffin; the top part of the wick extends out of the wick tube of the lamp burner, which includes a wick-adjustment mechanism. Adjusting how much of the wick extends above the wick tube controls the flame. The wick tube surrounds the wick and ensures that the correct amount of air reaches the lamp burner. Adjustment is usually done by means of a small knob operating a cric, which is a toothed metal sprocket bearing against the wick. If the wick is too high, and extends beyond the burner cone at the top of the wick tube, the lamp will produce smoke and soot (unburned carbon). When the lamp is lit, the paraffin that the wick has absorbed burns and produces a clear, bright, yellow flame. As the paraffin burns, capillary action in the wick draws more kerosene up from the fuel tank. All paraffin flat-wick lamps use the dead-flame burner design, where the flame is fed cold air from below, and hot air exits above. (Source: Wikipedia accessed 24 Nov 2023) This lantern has a circular heavy green glass base for holding the paraffin. The base has a 12mm green glass handle. There is a small clear glass chimney with a fluted upper edge and some bubbles in the glass. The metal burner and wick holder has four metal prongs to hold the glass chimney in place. The round metal wick winder is functioning. There is a small amount of residual paraffin in the base. The flat wick is made of cotton.There are no markings to indicate the manufacturer.paraffin lamp, flat wick lamp, domestic lantern -

Functional object - Bellows, 1862-1875
This bellows was used at the Warrnambool Racecourse by Master Farrier, Brian Chapman (1931-2017), during the 1970s but its history before then is still being investigated. The bellows have continued to be used from 1978 at Flagstaff Hill's blacksmith's workshop. Even today, in 2021, this same bellows are used by a volunteer blacksmith as he demonstrate the skills and tells of the importance of the blacksmith trade to colonial Australia. This 1860s double-action bellows is a typical form of blacksmith's or shipsmith's bellows. The end is forge-fitted with an iron nozzle or tube, called a tuyere or Tue iron, which concentrates the air to fan the fire or furnace. Tuyeres were traditionally made of cow horn. The double-action design of this bellows efficiently moves air both in and out of the chambers in the one movement of the long handle. The bellows was manufactured by John C. Onions of Birmingham, England, between 1862 and 1875. The stamp with the text, Gold Medal 1862, was also used on the business’ advertising. In 1875 the company was registered and began using the name John C. Onions Limited. JOHN C. ONIONS - John C. (Collingwood) Onions (1841-1904) was the son of a bellows maker of the same name. Onions (born 1841) and his wife Helen married in 1867 and they named one of their children John Collingwood Onions (1868-1913), as was the family tradition. He was well known as a Birmingham manufacturer of patented bellows and other forge-related equipment. He sold to the wholesale and retail markets for both local and overseas customers, including the British colonies. An 1862 advertisement points out that John C. Onions was a “Bellows manufacturer and contractor to Her Majesty’s Honourable Board of Ordinance” and His Imperial Majesty the Emperor of the French [Napoleon Bonaparte]”. The advertisement includes a sketched portrait of the Emperor Napoleon III, and an Imperial Autograph Letter dated May 23, 1854, from Napoleon, Palace of the Tulleries to Mr J C Onions of Bradford Street, Birmingham. In 1863 the company registered a patent on portable forges. In 1871 there were eight employees. John C. Onions Limited became a registered company in 1875. In 1876 an advertisements included that the company were smiths for hearths and tools in general and showed a row of six medallions including one with “Napoleon III, Emperor” and his portrait, and another “ _ _ _ 1862 MEDAL”. Their advertising motto was “For Excellence of Quality”. In 1885 the company merged with William Allday and Sons to become Allday and Onions. This mid-19th century bellows has local historical significance as it were once used by blacksmiths at the Warrnambool Racecourse in the annual racing event that continues today. This bellows is significant as a working example of equipment used in the 1800 and 1900s in the trace of blacksmiths and other metal working smiths. The bellows is technologically significant as it shows the progress from simple bellows to the double-action bellows, a time saving and efficient improvement. The manufacturer John C. Onions is historically significant as a family business that began in the 1600s and continued up until the 1980s.Bellows; large, oval, mechanical double-action smith’s bellows, manually operated, in working condition. The paddles of wood that form the top, middle sections and base of the bellows have flexible leather pieces attached firmly between them, forming airtight double lungs. Cut-outs in the panels allow the bellows to fill with air then force it out. A long handle is connected to pump the bellows and control the quantity and force of the air. The blasts of air are forced through the metal nozzle or tuyere at the end of the bellows and into the forge’s fire. Inscriptions are impressed into the wood on the upper paddle or board of the bellows. There are three circular stamps containing text. Text impressed in the wooden upper paddle of the bellows has been assumed to read “JOHN C.

photograph - Royal Australian Survey Corps Aero-triangulation Equipment, 1936 to 1952
Although it’s unknown when these two photos were taken, the South African Pattern Mk IV Slotted Template Machine was in service from 1936 to 1952. The machine was used to cut slots and holes in an acetate film medium. This template was then used to fit several runs of aerial photography to ground control points at a desired scale with a substitution of the templates in the assembly. Radial slots on the templates from central holes representing the photograph’s principal point (centre) were placed over hollow metal studs mounted over control points on the scaled base sheet. The studs represented the intersection of radial lines through common points of detail of overlapping photos. A pricker was used to transfer from the photo-points to the templates. The slotted template methodology was later used as an essential aero-triangulation exercise in advance courses conducted at the School of Military Survey.These three photographs are of a slotted template machine used in aero-triangulation. The first two photographs were printed on photographic paper and are part of the Army Survey Regiment’s Collection. The photographs were scanned at 300 dpi. The third photograph was captured from a collection using a smart phone. .1) and .2) - Photo, black & white, 1936-1952.

Photograph - Aerotriangulation Production – Army Survey Regiment, Fortuna, Bendigo, c1970s to 1980s
This collection of 14 photos was most likely taken in the 1970s and 1980s in Air Survey Squadron. The PDP 11/70 minicomputer shown in photo .1P was the operating system introduced in 1977 as the mainframe system for the control of the APC4, aerial triangulation block adjustments, SORA OP Analytical Orthophoto control, APR Analytical Terrain Profile Recorder computation, graphics, and general computing. Technicians used the Wild A9 Stereocomparator shown in photo .2P to accurately measure between pass, tie, and survey control points on aerial photographs. The Zeiss D2 Planimat Stereoplotter shown in photos .3P to .4P was used for analytical orthophoto control. It was introduced in 1972-1973 The Zeiss (Jena) Stecometer analytic stereocomparator for air photography shown in photos .5P to .11P and .14P was introduced at Air Survey Squadron in 1963. Aerotriangulation production was expedited using computers for analytical photogrammetric processes. The technician accurately measured between pass, tie, and survey control points on aerial photographs. Wild PUG4 point transfer devices shown in photos .12P to .13P were introduced in c1968 superseding the PUG2 devices. PUG4 devices were used by technicians to stereoscopically view the photography containing the survey control points and the mapping aerial photography.
