This is a small Waterbury shelf clock that runs with an 8 day time and strike movement.
Waterbury Mantel clock
This clock will require some bushing work on a couple of elongated pivot holes. A task I will get around to one day.
Rating Adjustment
This clock has a rating adjustment that can be adjusted from a small keyhole at the top of the face. The pendulum is obviously not the original one because it, too, has a rating adjustment screw that is redundant in a clock such as this.
This is an American clock, yet another Connecticut company from the nineteenth century.
