Elgin Factory stem / winding arbor for 20/0s grade 700 thru 705 movements

One Elgin factory stem for 20/0s grades 700 thru 705 plus 740, 742, 744 thru 803, 830, 833A, 900, 902, LONG thread, new in envelope. In the Elgin factory vernacular these are called winding arbors, but everyone else just calls them stems. See images for further details. I likely have several of these so the one you get may differ slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for an American watch I likely have it. Images do a pretty good job of representing the item.
