This is for a heavy (probably slate & bakelite) New Haven mantel clock. It is missing the decorative features on the front and sides of the clock.  The clock will only run for a few minutes at a time. Pivots appear to be tight but I was unable, I guess, to get it into a good beat. Key is not orginal and do not know if pendulum is or not?? Selling as is for parts or repair. With some work this could be a beautiful clock.
