This 2 foot 6 inch (762mm) gauge wagon was used for carrying explosives and was used with the Greenbat Battery loco. It was donated to the Walhalla Goldfields Railway on long term loan in 2013 along with a large quantity of narrow gauge trollies and light rail from Orica’s now closed munitions factory in Melbourne’s western suburbs. Orica - Deer Park Munitions factory Orica Deer Park in Melbourne’s west has been used since circa 1875 for various forms of manufacturing and storage of chemicals. Although the site is bounded by Ballarat Road, Station Street, Tilburn Road and the Western Ring Road, the current entry point for industrial operations is situated at Gate 6 of Tilburn Road. Operations include: • a specialty chemicals facility producing products for mining services operations • quarry services • other chemical manufacture activities. The Deer Park factory complex The factory complex is of historical significance for the major role it played in Australia's manufacturing and mining industries through the development of progressively more efficient and safer explosives. It also contributed to wartime production in ammunition, initiators and the development of synthetic ammonia production and construction of the Defence Explosives Annexe No 5 (later the Albion Explosives Factory) during World War Two. The factory complex is also of technical significance for the unusual and specialised design of many of the buildings and structures, both in the layout of the works and the individual design of buildings. Blast protection and safety measures such as mounds around the buildings, 'cleanways' and buffer zones between production areas were employed extensively. A characteristic of many production buildings was the elimination of cavities where explosive compounds could lodge. The combination of concrete barriers and light-weight construction was designed to direct explosion debris away from operators or other buildings. The narrow gauge tramway, which ran through the explosives section, is a rare survivor of nineteenth century materials-handling methods.

A porthole, sometimes called bull's-eye window or bull's-eye, is a circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armoured vehicles, aircraft, automobiles (the Ford Thunderbird a notable example) and even spacecraft. On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below-deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight and sometimes light-tight barrier (not in the case however). A porthole on a ship may also be called a side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the word "side scuttle" instead of "porthole" is meant to be broad, including any covered or uncovered hole in the side of the vessel. This porthole is a useful demonstration of naval technology to give people an insight into life at see. Small windows such as this example could be all people would see on long see voyage across rough seas. Commanding officers scuttle made of brass with glass opening windowmaritime technology
