The collection comprises of various makes of trucks, buses and emergency service vehicles. These vehicles were built to convey goods or people for either commercial gain, economic stimulation or as a public service. The collection demonstrates the development of general transportation, such as trucks, as well as highly specialised forms of transportation, such as fire engines. Indeed, the 1909 Merryweather on display was Adelaide’s first powered fire appliance.All vehicles in this collection can be generally categorised by their size or weight, both of which are much larger than those of the private motorist’s requirements. Some of these vehicles carry decoration or signage specific to the type of transport conducted. A number of these vehicles, such as Harry Monsoor’s Hawker’s Van, also reflect the lack of commercial infrastructure within the outback areas of South Australia and the resulting requirement for mobile commercial activities within this region.
