This model was found in the collection of Bay Steamers Maritime Museum. It is not knowt who created it but it is supposed that it was constructed to educate the many masters of the Wattle in the operation of a steam engine - a not so common mode of power these days. A Bay Steamers Maritime Museum examined the model in March 2012 and discovered that is was in poor repair. Using his existing knowledge, and with reference to some historic texts, he made some repairs and returned the model to working order. Here is his anaylsis of the situation as an excerpt from the Bay Steamers Maritime Museum newsletter Steamlines May 2012 "I was confronted with a model of a steam engine used years ago as a training aid for hopeful steam engineers. Already having a knowledge of steam operations, I considered a museum write-up for that model a ‘piece of cake’. However, on turning the model’s crankshaft, the valve timing seemed ‘out of kilter’ with the movement of the piston. Problem was that the two eccentrics on the crankshaft were not properly secured to it. Eventually I fastened the two eccentrics to the crankshaft where I felt that they should be and then realized that one of them had a chain-driven valve-timing device attached. This would be adjusted while an engine was running to achieve best performance and fuel economy whilst in operation by accurately controlling the period of time during which steam under pressure from the boiler would be admitted to the cylinder and give greater time for the steam to expand in the cylinder, move the piston and turn the crankshaft and thus, drive the attached apparatus. When the valves were correctly set up it was then possible to get the model to function properly.The model comprises a green section, which is the actual the model mounted on a brown painted board. There are two parts of the model, painted white representing the steam passages, and black representing the cast- iron portions of the cylinder-block casting, and of the main valve sliding between the cylinder a second sliding valve. Of the black portions, one slides back and forth being connected to a rod which is connected to an eccentric clamped to the crankshaft and is the nearer to the flywheel of two eccentrics. This eccentric is attached to the crankshaft at an angle of 90 degrees to the crank-pin attached to the flywheel. To operate the model simply turn the flywheel by means of the handle attached to its crank-pin. A second eccentric is also attached to the crankshaft, further away from the first eccentric, and it is adjusted to operate 90 degrees from the first eccentric (that is, 180 degrees from the crank-pin) A piston (painted silver) is located in a plastic cylinder and has a piston rod which passes through one end of the cylinder, (in actual practice a steam-proof gland seals the cylinder against loss of steam) terminating in a cross-head slide between four rails guiding it. From this cross-head, a connecting rod joins the piston-rod to the flywheel via the crank-pin attached to the flywheel which is part of the crankshaft. (In actual practice, a flywheel may not be used, particularly in a multi-cylinder engine.) The white portions of the model painted nearest to the cylinder represent the two steam ports cast into the main cylinder block, whilst one section painted in between those two represents the exhaust outlet (which may be connected to a condenser to conserve water, or to the open air). The main slide valve has three white-painted portions painted thereon. It has two white-painted marks representing the steam passages to the steam ports into the cylinder, and a third section in between the other two, being that part of the valve through which exhaust steam passes in line with the ports in the cylinder block. By rotating the flywheel, the operations of an engine will be observed as steam is admitted to the main valve via the gap between the two jaws of two moveable portions of a second sliding valve which is operated by the second eccentric attached to the crank-shaft. This eccentric is used to finely tune the valve timing of this model to obtain best running results of an engine. There are various methods used for reversing a steam engine. model compound steam engine, steam engine, model, crankshaft, valve, flywheel, wattle, engineer, eccentrics

This small barrel looks well used. Unfortunately, the inscription on the barrel is indecipherable so its story is a mystery. However, the bungholes on the side are a clue that it was once used for storing liquid, likely to have been liquor. Barrels have been used over many centuries for transporting and storing a wide range of dry and liquid goods. They are made by tradesmen called coopers, who use heat and steam to bend and shape the wood to suit the work in hand. They add metal reinforcing, handles, spouts and suchlike, to complete they process. Their produce also includes buckets, casks and tubs. Ships transported bulk liquor in their cargo, stored in wooden barrels. The barrels' round shape allowed them to be easily moved by rolling them into place. The body's shape gave the barrels added strength and the iron bands helped the wooden sheaves stay in place. The tops and bottoms allowed for easy grip. The bungholes gave access to government representatives, who would sample the contents, measure the alcohol percentage, and charge the appropriate duty or tax; the process was called Ullaging and the instrument they used was a Hydrometer. Hundreds of barrels of cement were imported into Warrnambool in the late 19th century for the construction of the Warrnambool Breakwater. Barrel-shaped concrete blocks are still visible at shipwreck sites such as on the LOCH ARD wreck, which carried cement among its cargo.This small barrel is representative of 19th century containers used for transportation and storage of liquid such as liquor. It is a historic shape that is still used in modern times.Barrel; wooden barrel, cylindrical shape with metal bands or ribs for reinforcement. The side has two bungholes; one has a bung or stopper.

Long term loan from Neurological Society of Australasia Museum of Neurosurgical Instruments , South Australia Catalogue with Historical Commentaries Second Edition January 2006 Copy located at RACS MuseumSTUART MORSON'S MECHANICAL INJECTOR FOR ANGIOGRAPHY. Stuart Morson(1913 - 1980) of Sydney had this injector constructed in or before 1952. It is said that it was not used much. The injector embodies two 10 ml and two 20 ml Record syringes coupled to a single delivery system. Each is operated by a piston. The pistons are driven from cylinders drilled in a metal block within the casing of the injector; the motive power must have been hydraulic or pneumatic pressure delivered through a manifold with taps allowing each syringe to be worked in isolation. The casing also contains two linked micro switches operated from a distance; it is unclear what was the role of these switches, and it is possible that a component of the unit is lost. JB Curtisl stated that a mechanical injector was devised in 1949 for serial angiography by his collaborator Schuster, but was not felt to be safe enough for use. For many years, neurosurgeons and neuroradiologists preferred to inject by hand.

This cylinder was constructed for the postage of two documents (0060.2 and 0060.3), to notify the family of Pte James Thomas Newton (945215) 3rd Battalion, Australian Imperial Force, of his passing. The documents appear to be addressed to M A Newton, though James Thomas Newton's next of kin is listed as David Newton, his father. James Thomas enlisted on 18 July 1916, joining the 3rd battalion, first in "B" Company and . James Thomas' service records indicate that he died on 9 October 1916 in a field hospital, Liverpool, NSW. He was ailed by bronchial pneumonia for 13 days before succumbing to the illness. A telegram suggests that the family were notified on the day of his death and received the cylinder and documents in the post 6 years later. Cream coloured card paper rolled into scroll for transport inside card cylinder (0060.1). Certificate is printed with standard text and British crest above which is a "G V R" indicating the certificate was issued by King George V.

The VN Commodore was available in Executive, S, SS, Berlina and Calais specification levels, although a more basic SL model (opt. code A9K) was supposedly offered to government and fleet buyers, as it was not officially listed as part of the Commodore range. Changes in the relative values of the Australian dollar, the Japanese yen, and the US dollar made it impractical to continue with the well-regarded Nissan engine of the VL. Instead, Holden manufactured their own 90-degree V6 based on an old Buick design from the US, although initially it was imported. The 5.0-litre V8 remained optional and received a power boost to 165 kW (221 hp). Both these engines used multi point GM EFI and the V6 using 3 coil-packs for ignition. Holden and HSV developed this car as the basis for racing in Group A Confederation of Australian Motor Sport events. While the minimum number of cars built to qualify in Australian Touring car Championships, with modified body kit, brakes or engine is 500, only 302 VN were built but CAMS granted an exemption allowing them to compete.Holden and HSV had worked hard to develop this car to be a serious competitor to the Skyline, Ford Sierra and the BMW which had dominated in the previous years. This was to be the Holden’s answer and coincided with the return of Peter Brock back to the Holden team from 1987.Mechanically the cars were fitted with reworked version of Holden’s 4.9 litre V8. The engine block was cast for additional strength, modified cylinder heads roller rockers and high fuel flow fuel injection was applied. Output was 215 kw at 5200revs and, though at today’s standard, that is not that much it was very impressive at that time. The drive was through a six speed ZF gearbox with a heavy duty racing clutch and a limited slip differential.Under the Hawke government's Button car plan, which saw a reduction in the number of models manufactured locally, and the introduction of model sharing, the VN Commodore was rebadged as the Toyota Lexcen, named after the late America's Cup yacht designer, Ben Lexcen. Subsequently, the Toyota Corolla and Camry were, similarly, badged as the Holden Nova and Holden Apollo.Red executive 4 door sedanHolden Lion and stone emblem grille centre, Commodore boot LHS, Lion and stone emblem boot RHS.vehicle, vn commodore, holden, car

The wooden pattern is part of a set that are stored in a strong wooden crate. It was used at Briggs’ Brass Foundry for making sand casts. It may fit together with one of the other patterns with a similar outline. The traditional craft of sand casting is over 2000 years old. The handcrafted process produces brass and copper alloy goods that are well suited to marine use; bells, boat hooks, cowls, propellers, handles, lids, rowlocks, hooks, letters, bolts, rail holders, brackets, deck plates, flanges, rudder guides, portholes and covers. Briggs’ Bronze mixture is a copper-based alloy made from local ingots of copper, tin, zinc and lead in carefully measured quantities. The finished product is non-ferrous and can last indefinitely. The crate of patterns was donated by the Briggs family in the early years of Flagstaff Hill, along with other related items such as brassware, tools and machinery. The donated items were displayed in a simulated Brass Foundry in the Village along with other working crafts, trades and services found in a Maritime town. The items were on show from the completion of the building in 1986 until 1994 when the building was repurposed. The patterns represent the trades of foundering and metalwork, both supporting maritime industries such as shipwrights and boatbuilders. Farmers, manufacturers and other local industries also needed the castings made by foundries. The Brass Foundry included a historic Cornish chimney set up as a working model, to tell the story of smelted metal heated in furnaces then be poured into the sand moulds. This chimney was made from specially curved bricks and is now about two-thirds of its full height when originally located at the Grassmere Cheese factory. The craft of sand-casting from carved wooden patterns to create metal is an example of skills from the past that are still used today. The foundry pattern set is significant for its association with brass foundries locally and generally in coastal areas of Victoria. Marine industries such as ship and boat building rely on good quality castings for their machinery, equipment and fittings. Briggs Brass was especially formulated using non-ferrous metals to ensure their longevity. The patterns are associated with the long-running firm Briggs Brass Foundry that specialised in cast goods for the marine industry, ready to supply the needs for once-off or mass-produced items. Their products would have been fitted to sail and steam vessels along coastal Victoria including Warrnambool. Briggs Marine was also a bell-founder specialist and is also associated with the Schomberg Bell at Flagstaff Hill, having restored it to is former state as a fine example of the bell from a luxury migrant vessel from the mid-19th century.Pattern; thick square mostly unopainted wooden block with a solid half-cylinder added to the top, which has rounded shoulders.

The Canadians developed a machine that used "ping pong balls" instead of cylindrical incendiary capsules and, in 1977, the FCV purchased a Premo machine for evaluation. The 32mm-diameter balls were made from high impact polystyrene and contained 3.5g of potassium permanganate. They were injected with 1ml of glycol which would ignite after a short delay The first Premo machine used four slipper blocks, which were loaded via a hand-operated hopper which, when rotated forward, the balls would be fed into four feed chutes to individual slipper blocks. Each slipper block has an opening allowing individual balls to enter and exit once injected. The original design of the machine was not suitable to meet the burning objectives and a number of modification were necessary. Following close inspection and field testing it was clear that utilising four slipper blocks was excessive and would generate too much fire. It was acknowledged that satisfactory spacing could be achieved by using just one slipper block. Selective spacing could be achieved by the speeding up or slowing down of the slipper block transferring the capsules during the injection process. Regulating the speed that the injected capsules were being dropped controlled the amount of fire created on the ground. This machine was the result of many years of experimentation at AltonaSignificant development of aerial incendiary machines enabled expansion of the fuel reduction burning program across Victoria.Aerial Incendiary machine for use in helicopters Modification at the Altona workshops over many years by Barry Marsden forests commission victoria (fcv), planned burning, bushfire, bushfire aviation
