SWCC Western Union Oak cased clock about 21" square Type F Mvnt. Are Pends and Bobs available for this clock. Or can you give the measurements for the pend and the size and weight of the bob. Thanks sparkplug 85
Given your SWCC case measurement, the movement was originally a 120 beat with a sixty tooth escape wheel.
Many of the wood cased clocks had wood-stick-brass covered zinc bobs. Used ones are available. Does your case have a brass beat plate? The middle of the scale is where the dart on the pendulum should extend to.
I will weigh one tomorrow and post its dimensions.
There are some clues: length of the verge crutch and tooth count of the second wheel....that belie 120 versus 140 beat movements.
If the case is really old, it may have the kind of movement code stamped into the bottom inside board ie: F L etc and the ohms of the sync coil.
Much thanks for the help. Label says 120 beat. I was able to cobble together a make shift rig and was able to get the movement running. There is a plate that I guess is the beat plate. Will try and get some pics thru it has been a good while since I used the forum.
