I am trying to decode a vehicle number from the data plate on the firewall for a 1939 one twenty. However, the number is C301141 which appears to possibly be a theft proof number? Could this be a replacement data plate and the wrong number was stamped? I appreciate any information. Thank you

It might be an Engine Serial Number? Although 1940 had a "C" prefix while 1939 had a "B" prefix. Check the Serial Number stamped on your Engine. Just food for thought.

If that's the number stamped on the boss on the driver's side of the block, then it's an engine number but it should not begin with C0 as far as I know. If it IS an engine number, as Mal said, it is a 1940 engine which began with C for that year while 1939 began with B but none had the first digit as 0. Maybe photos of the data place and of the car itself would help.

If it's the large raised number stamped directly into the firewall, that's the Theft Proof Number.

But, many data plates were replaced over the years and sometimes stamped with incorrect numbers.

A proper 1939 Vehicle Number will be in a 12##-#### format. (Unless it's custom bodied car, which can differ)

But, the number you listed is more than likely a theft proof number based on it format.

A theft-proof number of C01XXX corresponds to 1953 vehicles.

Thank you to all for the quick response. I will investigate all suggestions! picture added to original post.
