I recently repaired this “Seth Thomas Metals No. 3” oak shelf clock made around 1900. I overhauled the movement and did a little veneer patching.
Repair job 8667. The pinion wires had a lot of wear, and so I replaced the wires in 6 pinions. I polished the pivots and installed 18 bushings.
The mainsprings are the originals:
Time Mainspring 3/4 x 0.018″
Strike Mainspring 3/4 x 0.0175″
The movement is the No. 89, but made before they called it that, and it is stamped 8 1/4.
