Elgin Factory stem / winding arbor for 6 ligne Grade 875

One Elgin factory stem for 6 ligne Grade 875 movements, new in sealed packaging. These 6 ligne movements are ETA 2442 ébauche based so this will fit movements other than just the specified Elgin. In the Elgin factory vernacular these are called winding arbors, but everyone else just calls them stems. See images for further details. The stem did not have any moisture protection so it will need some minor cleaning before use. 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.
