This cute little Seth Thomas mantel clock is 9 13/16 inches tall and 7 3/8 inches wide. It has a white enamel dial, and the minute hand is 1 3/4 long. It strikes the hour and half-hour.
The model B-48-J movement in this clock looks like a forerunner of the No. 120 movement in my earlier post. Superficially they look similar, but the gearing and escapement are different. Both movements have stationary barrels to contain the mainsprings. This movement has the barrels mounted to the back plate, but the 120 has them mounted to a removable lower front plate. This means that one can replace the mainsprings on the No. 120 movement without separating the plates. This movement (B-48-J), however, requires disassembly to replace a mainspring.
Repair job 5737. A previous repair shop had installed bushings that were way too tall (3 times the required height). I polished the pivots and installed proper bushings. I also straightened bent teeth on the canon pinion, reduced the hand-set tension (to make the minute hand easy enough to turn) and replaced one missing pinion wire (or trundle).
