Wow, I like that spring belt for the bobbin winder. I think it was a Franklin that had two belts, one for the machine and one for the bobbin winder.
It looks like it has one of the connectors that might be called Manhattan or Chicago plug which are no longer available. Some of them may screw apart so could rewire it. I'm guessing that it does not actually have a motor boss. I'm also guessing that it may not have an actual Singer motor, but could be. I think I have seen a foot controller like that - maybe even a Singer one.
No, I don't have any advice for you, other than to rewire and enjoy.
