Hi Harry:
I'm restoring a 1953 Yugoslavian copy of a 1942 Zis 3 76.2mm Russian cannon. It too has skinny 5 stud 20 inch rims on it. I just had the rims sand-blasted and painted so I'll post some photos and measurements. I'd be very interested in finding out what rims the Soviets copied- Ford, GM, ??
Mike
