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. Sadly, the SHORT thread has the same P/N so if you can use a short let me know and if I have any available I'll save you a buck.  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.
