I am looking for information on the Sangamo clock Type B-7. I have the bulletin referance Vol38-Issue305, and page783 which is a great help on the background. I want to know about the motor and the electrical connections on the back of the case. Is this motor replacable or rebuildable? It is an interesting approach to the transition between electric and mechanical clock. Any information would be appreciated.
