Elgin Factory stem / winding arbor for 8/0s grade 555 movements

One Elgin factory stem for 8/0s grades 555 (plus I believe 556 and likely others), new in packaging. I have a note that says these particular ones are of the oversize variety. 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.
