Elgin Factory stem / winding arbor for 8/0s grade M112 (UTC 229) movements

One Elgin factory stem for 8/0s grades M112 which are Swiss UTC caliber 229 based movements usually found in the Elgin Sportsman Mens wrist watches of the late 1960's, new in sealed packaging. In the Elgin factory vernacular these are called winding arbors, but everyone else just calls them stems. 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.
