Help Needed on Broken Pocket Watch Escape Wheel Pivot

[specks]

Hi Everyone,

I'd really appreciate some pointers if possible.

I have a key-wound pocket watch with a broken escape wheel pivot.  The movement seems to be entirely anonymous, with no easily identifiable markings to indicate the caliber or manufacturer - with the exception of two single characters - a '6' and a '9' or they could be stylised single quotes - and a movement number.  I've measured the movement's diameter at approximately 41.5mm or 18.5 ligne.

For now, I'm ruling out re-pivoting as I don't have the required equipment [this will follow at some point, I'm sure], so on the assumption that the movement cannot easily be identified and a replacement wheel sourced, are there options such as using my staking set to remove the arbor and replace it?  Replacement arbors don't seem to be readily available - is this a reasonable statement?

If I can find a replacement arbor of the same length and diameter, presumably the pinion is a friction fit over the arbor and so with care, it should be possible to complete remove the old and re-fit a new pinion?

Thanks for any support all.

Steve.

Theoretically yes it is possible, assuming the pinion is a friction fit. I would carefully measure the existing one first in case of damage when removing it. Then one could be made on the lathe, or a replacement found, and staked back in. Not knowing the maker or anything will make finding replacement parts quite tricky. I'd post some pictures and see what the community thinks.

Thanks khunter.  Photos seem to be failing but are a standard format.  I'll come back to you shortly.
