I have been reading Ball-related posts under American Pocketwatches. I read under one such post that parts for Ball watches could be ordered. Is that true? I thought if one were missing a part one would need to remove it from a junkernot order it from someone. More specifically, I'm looking for a regulator. (I listed a query under Parts Wanted).) Is there a supplier for Ball parts? I thought any source for parts for any American pocket watch dried up a long time ago.
