I'm repairing an electric clock for a friend and need a Sangamo S1 electric motor - patent number 1933 - 591. Any suggestions?

Old electric clock motors are very hard to find. Sounds like the clockmaker is out of business as electric clocks are a thing of the past.

Have you considered replacing the guts of this clock with an AA battery clock movement? Much easier to find.

I did at one time find a source of antique clock parts, but this could offer a better resoration option: Clockworks.com Clock Kit Parts Movements
