I started off trying to find the International tipper detailed in post No.9 by Mike Kelly through the AWM, ARN books but sofar haven't had much luck. BUT I did find a few pages of impressed vehicles, which were impressed in both the Northern Territory and New Guinea. The quality of my phone photos is not too good but here they are. There are some interesting vehicles and it seems they would grab anything. In the New Guinea list there is mentioned a 1925 Chev Tourer, a 1926 Chev Ute, a 1927 Buick Roadster, a 1928 Ford Sedan, a 1927 Dodge Van, a 1928 Chev Van and many more. In the Northern territory list the vehicles are a bit more modern, the oldest (I think) is a 1935 Ford Sedan.
Regards Rick.
