Seth Thomas made this tambour mantel clock that says “Plymouth” on the dial. Seth Thomas marketed clocks under the Plymouth name around the 1930s and 1940s. The movement is Seth Thomas movement No. 89IL dated 36 10 (October 1936). It strikes bim-bam on each quarter-hour (one, two or three times) and at the hour strikes the number of the hour on a single gong. The dial is aluminum and the case is mahogany veneered.
The following two Plymouth catalogs show this clock:

Repair job 8760. I didn’t do a full overhaul on this clock, just a disassembly and cleaning, burnished one pivot and installed two bushings. The escapement, strike point and hammers needed adjusting.
This movement has rack and snail striking (see picture two above) instead of the usual (for American clocks) count wheel striking. A cam on the center arbor lifts one hammer as the hour approaches, and lets it down afterward, so the hour strikes on one just one hammer. The third picture above shows the hammer that is out of action at the hour.
