I overhauled the movement of this clock recently. One of the teeth on the escape wheel was too short, so I inserted a new tooth.
Both mainsprings are original Seth Thomas mainsprings that measure 0.0165 inch thick. The strike speed is adequate, but I wouldn’t want the mainspring to be much weaker. The pendulum takes a fantastic swing, about three times the escape arc. The time mainspring could be quite a bit weaker and still have plenty of power.
This clock appears similar to the College Series “New York” with a different base and glass. It is also very similar to one of the “Capitol” series with a different base and glass.
