I am having a bit of a problem trying to figure out the origin of a box full of small watch parts that I won in an auction lot last year. They were labelled as "Heuer chronograph" parts, and the auction lot contained some Blancpain Fifty Fathom Bund parts (the reason I bought it), so I figured they were probably used or service parts from a Heuer Bund. The pushers and crown look right, and of course the sealed parts I can identify, but do any watchmakers here recognize any of the loose parts ? Sorry to ask, but I have got as far as I can on my own...
