Elgin Factory stem / winding arbor for 8/0s grade 933 Movements

One Elgin factory stem for 8/0s grade 933, new in sealed packaging. In the Elgin factory vernacular these are called winding arbors, but everyone else just calls them stems. This grade was based on the FF caliber 55-4 movement. See images for further details. 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.
