SSsssteamer,
Well according to the DMV in North Carolina, Georgia, Nevada and now California (in that order) say it is. The number on the cross member reads, … 44646569
Paperwork that came with the car which I verified by phone with Nevada DMV, shows the locations to look for a 1931 VIN. and my chassis with that number is from March 1931.
Ref to pic.
I read online somewhere, and it figures I can't find it right now, but it basically said, that around the time my car was born things were changing fast as the A's were coming to an end. They pretty much used what ever they could and did what ever they had to do to get the parts out the door. Shoot, some cars frames were never even stamped with any numbers.
Regards
Bill
