I found a naa file (over 300 pages long) relating to the disposal of Lend Lease vehicles in Australia.
One page mentions a single Dodge T203B 4x4 truck that was acquired in the Middle East.

Was this truck a ex-French contract truck, diverted to Britain, shipped to the M.E. , then acquired by Australian troops and shipped to Australia ? Seems that the Dodge was located at Ryde vehicle park in Sydney waiting disposal.
The army were unsure of the value or price , they decided on 550 Pounds . The Dodge was probably sold to the Chrysler Aust. dealer: Harden & Johnstone in Sydney. It may appear in the AWM 126 books somewhere.
Another odd one mentioned in the file is a 1 Ton GS with Marmon Herrington kit.
