This electric clock motor is from the Synchron line manufactured by Hansen in November of 1949. its body is made of brass, and has light patina on it. personally, I think that adds age and personality to the look of it. But if that's not your cup of tea, it will easily polish back to mirror brass. It is a model 600 runs on 110v AC power. The tag says 1 RPM and 60 C. It also has a viewing window so you can see the internal parts spinning while it's operating. The gear teeth are impeccable and appear unused. I have tested it, and everything appears to operate as it should.
