All the following is from my 1948 Chevrolet Truck Restoration Guide.
The GVW of 8800 on the VIN plate and the wheelbase of 137" both say 1-ton, of course. That truck (GVW 8800) had the highest GVW of any of the 1-tons and came with 7.00-18 tires. Those tires were needed to specify it as GVW 8800. What rims do you have?
Does the box look original? The GVW 8800's were sold as stake trucks among other configurations w/o a box.
Anyway, a guy grabbing an "R" stamp instead of an "S" for 1-ton would explain a lot.
