Hamilton Factory Stem / Winding Arbor for 20/0s & 21/0s Hamilton No. 614530

Hamilton Factory Winding Arbor (stem) for 20/0s & 21/0s Movements, Grades 721, 995, 995A, 997, No. 614530, new in envelope. Will need some light cleaning before use. I likely have several of these so the one you get may vary slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
