I bought a lot of staffs from a closing watch supplier. Most are 16 and 18 size.

HAMILTON, ELGIN, WALTHAM, HAMPDEN, HOWARD

Many have 4 numbers...I cannot discern for which movement they belong to.

My SWIGART book is no help...I imagine many staffs are before publishing of this book.

look in the topic on chapter 185 JOhn Duvalls helping hands tutorials and the topic (American pocket watch staff dimensions),, i think this would help a lot..if you can also post some of the #,s in question and i am sure someone can help..

Daniel,
I tried to post the Hamilton staff numbers, but it said the file was to big, check your e-mail.
