Here’s a Seth Thomas 1948 electric mantel clock with Westminster chimes that I repaired. The mahogany case is 9 1/8 inches tall and 19 15/16 inches wide. The minute hand is 2 1/2 inches long.
Repair job 6382. I polished the pivots and installed 25 bushings. I installed a replacement time 5th gear, as it had bad tooth wear and a loose hub.
After repair, the motor was moderately noisy. I found a better used motor which was much quieter. After repair, the chime mainspring wound 6 1/2 to 7 turns until the brace slipped, and the strike mainspring wound about 7 1/4 turn to slipping.
The label on the back door has the date code 48-2 (February 1948) and the movement has the date code 48-1 (January 1948).
