For estate reasons, I’m trying to determine the value of a few of my late father’s clocks. He was a long-time NAWCC member and Fellow of the British Horological Institute. This wall clock is marked “Wood Glasgow” on the dial. My father described it as follows: “8-day English Dial – 12” Roman dial – fusee with gut chord – cast-brass bezel – mahogany case with mahogany veneer dial – 15” O. D. – circa 1850-1875.” I can add that the case has two doors and is held in place with four wooden pegs. I have the pendulum and it runs for a few minutes when wound. It also runs for hours if the pendulum is removed and the clock is laid on a flat surface. Any information you can give me would be much appreciated.
