Kuno,
Sorry, I don't have clear pictures of 1940 Ford trucks, other than those UK and Canadian built 3-tonners shown in the threads "
Desert Wreck 4, FORD V3000" and "
Ford US trucks for RAF, Egypt". Main differences with US built ones would be the wheel/tyre combination and cargo body.
In the latter thread I made reference to the Ford 30-cwts used by the Sudan Defence Force, as mentioned on
http://www.fjexpeditions.com > The Kufra Convoys. Reading Andras Zboray's message I now understand these Ford 30-cwts were actually CMP F30's, not militarised conventional 1½-ton Fords. Therefore, the remains of the 1942 model Ford (pic below) must also be one of those trucks used "after August 1942 [when] every possible vehicle had to be pressed into service to supply Kufra".
Please keep those pictures coming, I think it is great to see these truck remains placed in their historical context!
