1940 - 50s GE Motor wiring

I have had this motor for about a year now. I found it in a barn, and I guess it was my great-grandpa's. I cosmetically restored it, long story short I'm varnishing the windings tomorrow. I'm a bit confused by the terminal plate for this motor. The original wiring was neutral to 4, hot to 3, and a wire ran from 3 to 1. It worked in this config. I wired it to have hot on 3 and neutral on 4 and nothing else, it also worked like this. Im not sure what post 1 was used for, though. Could it have been for a start cap? The contacts would be connected when the start winding was not in use, so that's the odd part. Polarity in this case obviously doesn't matter. Any ideas?
Specs:
1/6hp
1725rpm
3.8a
Model 5KH43FD12 (KH model so no cap)

I doubt there was a start cap at 1/6hp. It is more likely a shaded pole, and the phase shift needed to get it started is in the wiring. If it isn't, it would be a split-phase, which is like a cap start, but without the cap, and just using the magnetic effect to get it started.

If you switch post 1 and 3, I would be willing to bet it will reverse, which would be the point of the second pole.

It's split phase smaller diameter wire in start winding causes the shift.

Yes, it's split phase. I just got done varnishing the windings, too. I also edited the model number in my first message. I entered the model for one of my other motors by accident.

Well I got it looking decent, my goal wasnt to make it look brand new. Id rather have it look somewhat used. I varnished and painted the windings too. Still don't know about the wiring though.
