After the war the Swiss Army acquired quite a bunch of Ward La-France and Diamond T Wreckers. These were used for tank recovery and on airfields.
Unfortunately, all these wreckers had the same manufacturing year stated on their "Swiss" building plate. Here are some wreckers I know of:
Ward LaFrance (2nd number is the chassis number)
1943, 535364, M1A1 Model 1000 Series 5
1943, 422090, M1 Model 1000 Series 2
1943, 545315, M1A1 Model 1000 Series 5
1943, 434370, M1 Model 1000 Series 4
Kenworth
1943, 52287, Model 570 (1941)
Diamond T969
1943, 969B0005
1943, 969A0988
Does anybody know how/where I can source these actual building dates (month/year)?
Thanks very much
Chris
