Wow! That takes some skill. You have my applause.Hi Mike,
I think you'll have a long search since nobody seems to stock them; the cal. 280 setting levers seem to be prone to snapping at the nib, and having just found two movements with the same problem, I've recently finished making one with its screw! As they have a boss round the threaded hole, they're rather awkward to make.
Regards,
Graham
