Expert Reply:
The 17-charachter VIN became the standard in the USA January of 1981. So you should have a 17 digit VIN on your 1987 Calkins boat trailer. Prior to this VIN's ranged from 5 to 13 digits depending on the manufacturer.

Can anyone give me a hint how could I trace my Calkins Escort tandem boat trailer specifications ie. type (catalogues etc.)? I’d like to register the trailer… but no VIN number anywhere. Trailer is ~23ft long tandem with bunk bed… made ~1985-1990? I have looked everywhere but all I can find is empty Calkins placard in the main tube

I have a Calvin’s boat trailer, manufactured August 1973. Have the serial number and Model number but can’t get it registered because I can’t find VIN.
