After 10 years of design and experimentation , the father and son team had bench tested their new 90-degree V-twin double-acting uniflow type engine and installed on the tray of a 5-ton Bedford truck . This truck was subsequently partially burnt out in the Ash Wednesday bushfires in 1983 while in storage on a farm in rural Victoria . The damaged but still substantially intact truck was collected by the National Museum of Australia and has been in the Mitchell Annex of the NMA since it was acquired
