Elgin Factory stem / winding arbor #6363 for 19/0s Grade 660 movements

One Elgin factory No. 6363 stem for 19/0s grade 660, 661, 662, 666, 667, 668 new in packaging, Refill #516. In the Elgin factory vernacular these are called winding arbors, but everyone else just calls them stems. See images for further details, and regardless what the package may say there's only one stem. 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.
