This Gilbert tambour mantel clock is dated 1928 on the movement. The case is 21 1/8 inches wide, 9 1/2 inches tall, and the dial is printed aluminum with a 4 7/8 inch time track. The movement is 8 day time and bin-bam strike on 2 chime rods.
The movement has removable mainwheel bushings, and the original mainsprings have open loops, allowing the mainsprings to be replaced without disassembling the movement. The original time mainspring was stronger than necessary, and I replaced it with a Timesavers no. 18790 3/4 x 0.0162 x 96 inch (the original time mainspring was 0.0177 inch thick. I retained the original strike mainspring in the clock (it is 0.0165 – 0.0168 inch thick).
I polished the pivots. Some of them, especially the mainwheel pivots, were very rough when the clock left the factory. I installed 17 bushings.
Repair job 5388.
