David they are not military style front ends but instead civilian models with black out covers on the headlights. They also have the larger heavy duty rear axle but a single wheel instead of duels. This is the same as the Polish Red Cross ambulance photo you put up some time ago.
So 1941 civilian LHD cowl/chassis units with a coach built body. 134in WB is my guess as well.
Another thing to note is the two to the Right have smaller wheels and tyres fitted as they appear to be lower to the ground at bonnet (hood) level.
very nice David thanks for sharing.
cheers
Cliff
