Both trucks are Lend-lease vehicles
First one is 4x6 no winch
Serial number plate is missing no original plates in the cab
Second one 6x6 with winch
(Gal wood winch in my opinion originally mount)
Serial number plate is missing no plates in the cab
But there is number on frame 4/4 452771 (or 4/4 457771) but I don’t think that it is original.

We have also plate from third vehicle very destroyed number probably is US6X4 60251
