VIN was not in existence in those days. There was a plackard with a number printed or embossed on it that usually accompanied a Bill of Sale and later titles. Numbers on the motor s were casting or part numbers and the same for the frame. Having lived in numerous states, it has been interesting to see the difference in how they handle this subject if you don't have a title they understand. The most interesting case I had was a 36 pickup that I had a title to, but of course I could not provide Fla a VIN number and would not transfer the Okla title. They would give me a VIN number for me to stamp on the truck and require a notarized certification from a DOT official. I moved to Texas before this was complete and they said "no problem! we will issue you a non-negociatable title (can't sell the truck). This worked for 3 1/2 years in Tex and another 3 years back in Fla ( they will issue tags without transfering title). Then it was on to Utah and I went for tags. In the ensuing discussion there, the wise lady said "Just show me the truck and a stamped number and I will give you a Permanant title." Well, my title now has the Frame number as the VIN number so I can claim almost any 36 Ford PU with a readable frame number. Beware!!
