This is a Seth Thomas “Sentinel No. 19” tambour mantel clock . The case is 20 1/8 inches wide and 8 5/8 inches tall. The painted dial has a 5 inch minute track and the minute hand is 2 7/16 inches long.. The back of the movement has the numbers “37-4” which I believe is the date code for April 1937.
It strikes the hour and half-hour on two rods.
Repair job 6048. I polished the pivots and installed 17 bushings. The mainsprings are both original.
Time mainspring: 3/4 inch wide by 0.0165 inch thick
Strike mainspring: 3/4 inch wide by 0.0167 inch thick
