I don't think I saw mentioned that little emblem on the side that says 10/20/30 (for my 60-66 era)
The 1-ton Chevrolet would say 30 1960 through 1972 after which we at the Stovebolt officially quit paying attention.
I'm not sure how GMC marked 1-tons in that era. Was it the same? I feel like I've seen the 1500/2500/3500 markings on trucks of that era and I assume they were GMC's.
The '47-'59 Chevrolet 1-ton's are 3800 and the GMC's are 250.
I've no idea how Art Deco trucks are marked either. Can anyone add that information?
