The pallet-fork on my M1870 is in bad shape, it was once broken in half and soldered back together, further having mismatched jewels on the ends. Likely another example of someone working on a full plate 18s. movement & allowing the pallet-fork to crash with the potance resulting in catastrophic damage.

I may be able to acquire a donor watch which is crown wind & pin set.

My watch is key wind & key set.

Both movements are 15j. hunters.

Does anyone know whether these parts are interchangeable?

Waltham's 1885 material catalog lists only one pallet fork so apparently the same part was used in stem wind or key wind models (and I can't imagine why not). I would expect the same part interchangeability as with most parts from that era, i.e. some fitting may be required -- especially the pivots.

Thanks Jerry.

Is the 1885 catalog available for download?
