This chassis was the only Thornycroft "Daring" double deck unit, imported into Australia. The body it originally had was very similar to museum exhibit 1187, the 1935 Albion Venturer Model 80. It operated for the Department of Road Transport & Tramways between 12 November 1934 and April 1941 as Fleet No.171 (Registered m/o 1371 later m/o 1171). Advice from a UK Correspondent in 2002 reveals that this chassis is the only one that has survived.

Due to the chassis being non standard, the bus was taken out of service in 1941. The body was removed and used as a replacement body for Leyland TD1 No. 698 (m/o 1698). This bus had previously had a very early double deck bus body with an open rear stair case. The Gardner engine was transferred to Albion No. 178 and the chassis modified for instructional use in the Driver Training School. The work was done by the Leichhardt bus workshops in the early 1950s. The chassis was shortened so that it could be accommodated in the available space at the Training School. Many of the mechanical components affixed to the chassis including the Leyland diesel engine, the gearbox and the differential were sectionalised for demonstration purposes.

Trainee bus drivers were instructed on the internal operation of a bus and shown the damage that could be caused by using incorrect driving techniques. For ease of operation it was wired up for electrical operation. The equipment was transferred to the new Dangar Street, Randwick driver training school when it opened in 1953. The apparatus was eventually regarded as outmoded as a training aid and was transferred to the Association for display in the Bus and Truck Museum in 1990.
