There was no such thing as a VIN in 1950, so don't expect any number you have, unless it was assigned much later by a DMV, to have the correct number of digits for a modern VIN. There was a body serial number on the data plate and a stamped engine serial number to the rear of the distributor. The engine serial number did not appear on the data plate except in Canada. In the U.S., the engine serial number was usually used for registration purposes in most states.
