Elgin Factory stem / winding arbor for 5/0s grade 791 (AS 1673) movements

One Elgin factory stem for 5/0s grades 793 which are Swiss AS caliber 1673 based automatic movements usually found in Elgin wrist watches of the early 1960's, new in envelope. 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 an adequate job of representing the item.
