Found this clock at an auction

All I know about the clock, is that inside on the works its says "1906" and the "Gilbert Clock Company, Winsted, Conn. USA".

In pencil on the back side is 10087 M. I would like to know more about the clock, and what value would it now have.

Thanks Steve and Bonnie Mattson, Lisbon, ND.
