39-53 GMC Master Parts Book lists an electric wiper motor part number 2113355 for EC 100 thru 350 models, which were late '46 models. But it looks nothing like your motor.

55-60 GMC Master Parts Book lists a 6 volt electric wiper motor for 55.2 trucks. Only 6v truck in 55.2 was 248 engine with standard transmission.
Part number is 5047825. HERE is one for sale on ebay. The seller has it listed for '54-'55.1 Chevys.

I don't have 54-55.1 GMC parts books.
