I just purchase my first model A. I just had a vin check prior to registering it. I noticed the frame number starts with 393XXXX ( the engine has a different number sense the engine was changed in 1998), which I believe was Sept of 1930. It also has the 2 piece splash aprons (1930). But it has the 1931 radiator shield and the round speedometer which tells me a late 30 or 31 speedo. From what previous registration show it to be a '31. So, I question what do I really have?
