Hi,
It's a colonial ship clock built buy the United Clock Corp., the model number should be on the back of the clock. I have model 811, yours looks like a earlier model, from what I see on the internet the model 811 prices out around $50 to $300, depending on the condition. Also from what I have been able to find on the Internet it looks like they were produced in the 1940's to 1950's
Model 811 by: Anonymous
Upsate: I opened up the back of the clock and it was stamped inside, APR 1965, for model 811. I removed the motor and cleaned it and it works fine, also bought some round elastic cord to restring it.

If you need to see the correct way to rig the 811 I was able to find a picture on the internet.
