The Germans bought some guns during World War I, but used them as infantry guns in direct support of the infantry where their light weight would allow them to move with the infantry. They complained that the guns were too fragile and didn't have a high enough muzzle velocity to act as an anti-tank gun. Considering that the guns were designed to be disassembled it's not too surprising that they couldn't stand the abuse moving through the shell-pocketed front lines on the Western Front.This particular Gun was captured by Australian Soldiers at the Battle of ST Martins Wood near Ypres in the 3rd Battle for the Somme. The German crew were all killed as were a number of AustraliansThe Skoda 7.5 cm Gebirgskanone M. 15 was a mountain gun used by Austria-Hungary in World War I. In German service it was known as the 7.5 cm GebK 15. Its development was quite prolonged as the Austrians couldn't decide on the specifications that they wanted. Initially they wanted a gun that could be broken-down into no more than 5 pack-animal loads to replace the various 7 cm mountain guns in service, but prolonged trials proved that the 7.5 cm M. 12 prototype to be the best gun. The guns were delivered beginning in April 1915 instead of the planned date of April 1914. For transport, the gun could be dismantled into 6 parts, generally carried in 4 loads. In addition, there was a gun shield fitted on some (perhaps many) such guns. ypres st martins wood skoda gun

Professor Arthur Barrington (Barry) Baker was the first Australian anaesthetist to gain a DPhil in anaesthesia. He completed his DPhil at Oxford University at the Nuffield Department of Anesthesia in 1971, titled, Physiological Responses to Artificial Ventilation. The Waveform Ventilator is the machine developed to illustrate his DPhil. The waveform ventilator was used in several scientific studies on 'the effects of varying inspiratory flow waveforms and time in intermittent positive pressure ventilation (IPPV)', published in the 'British Journal of Anaesthesia'. Professor Arthur Barrington Baker had an extensive career in research and clinical practice including holding the position as the Nuffield Professor of Anaesthetics at Sydney university (1992 - 2005) and also as the Dean of the Australian and New Zealand College of Anaesthetists (ANZCA) (1987-1990).The variable waveform ventilator is of national significance, due to its association with Professor Arthur Barrington Baker (Prof. Baker) the first Australian academic anaesthetist, and the representation of historical social themes and research and design, in anaesthesia. Historic significance – It is a rare type of ventilator in good condition and well provenanced. It is a tangible record of the beginning of the long established and distinguished career of Prof. Baker, the first anaesthetist in Australia to gain a DPhil. Prof Baker has a strong involvement in the Australian and New Zealand College of Anaesthetists (ANZCA) organisation. The object is a product of Prof Baker’s Doctorate of Philosophy (DPhil) on respiratory physiology and is associated with the prestigious Oxford University and the well-known Nuffield Department of Anaesthetics. It also represents the social theme of migration to England from Australia in the 1960s and 1970s to access and experience academic and artistic opportunities limited in Australia at the time. Scientific Value – The object is of scientific value as it offers major potential for education and interpretation in anaesthesia. Although ventilators are common equipment, this specific design and construct prototype is one of a kind, designed and used specifically for research purposes. A rectangular shaped object on a trolley with four wheels. The top half of the object consists of two panels, one of cream coloured painted wood, the other black plastic, both containing several dials of different shapes and sizes.

The cylindrical cardboard container with lid formerly contained a ventometer, a small simple tool for measuring wind speed. It consisted of a clear tube containing a small diaphragm which had a hole in the bottom for wind to enter. Once the wind entered the tube it pushed up the diaphragm, indicating the rate of velocity. Ventometers were common devices that have since been replaced by more sophisticated measuring equipment, such as digital air speed meters. Further information on this particular example, including perhaps the name of the manufacturer, may survive on the container but this has not been recorded. The small simple tool for measuring wind speed pre-dates the electronic devices at Gabo Island.Tubed shaped cardboard container with lid to house instrument for measuring.

The Bofors 40 mm gun, often referred to simply as the Bofors gun, is an anti-aircraft/multi-purpose autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well as by the Axis powers. The shells were manufactured according to a British design after it was discovered that the Swedish shells had much too sensitive a contact fuse, "which functioned on impact with rain drops". Although the shells could nominally reach out to 11,000 yards (10,000 meters), almost all the shells manufactured had self-destroying tracers that detonated the rounds at a range of 4000-5000 yards (3700-4600 meters.) This helped prevent friendly fire incidents or other collateral damage. In addition to the TNT bursting charge, the shell contained a pellet of powdered magnesium and aluminum as an incendiary. Production of ammunition peaked at 12 million rounds per month in the winter of 1944. Ammunition type Contact fused HE/incendiary fixed shell. AP shells were also available.

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.
