Good Call Spanky,
Found some other pics I took and was able to Zoom into the number in one of them, Gotta love the VIN Buster

Serial # : N53K025607
Mfg Year : 1953
Model : 4100 1.5 ton
Wheelbase : 137 inches
Plant : Kansas City, MO

The wheelbase must have been shortened up during the conversion. So have you got any pictures of the other one's you've seen? I'm curious what the winch should have looked like.
