Have just acquired an original 1942 Ford tudor sedan blackout. Have the serial number but no title. How is the most accurate way to determine the production date ? It is in poor but restorable condition. It appears to be originally painted black (not an olive drab car), so I'm guessing it was one of the last civilian production cars or possible one of the 104 wartime production cars for the Justice Dept. Plan to restore to as original as possible. There is no "Deluxe" or "Super Deluxe" plaque so I'm guessing that it is a Special. Not sure. It does have a radio antenna located at center top of roof. Any information would be helpful. Thanks, Jim H.
