Hamiliton Sangamo wiring

Hi,

I've recently been given the task of repairing a antique Hamiliton-Sangamo wall clock. Its model number would be L50131, I beleive its from 1956.

Anyway it has one black wire coming from one side of the gear assembly and 2 wires one orangish and one whitsh coming from the other. I'm curious as to the proper way to wire this?
