I would be interested in knowing the serial number of the machine. It’s probably going to be a 1920s model that came out originally with a spoke hand wheel and bobbin winder to match, and then was “electrified” later with the changing of the bobbin winder and hand wheel and an added motor. No way of knowing whether it was outfitted as a hand crank or treadle originally, but it could have been either since it has the hand crank boss (also called the “motor boss”). Later 66-1 machines with the boss in the casting were sent out in both configurations (crank and treadle).

Nice catch there!
