This is a Seth Thomas 8-day time and strike lyre-shaped clock movement made around 1865 (movement marked Plymouth, case label marked Thomaston). This movement has 4 train wheels on the time and strike side and uses 11/16 inch wide mainsprings. I installed a new time mainspring 11/16 wide by 0.0165 inch thick by 96 inches long from Empire Clock. This spring opens out to about 9 inches when first released from its clamp. This movie shows the escapement motion with the spring fully wound. The motion is good but not excessive.
