Elgin Factory stem / winding arbor for 11½ ligne Grade 938

One Elgin factory stem for 11½ ligne Grade 938 Sweep Second, Calendar movements, new in packaging. These 11½ ligne movements are FOR 89 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. These are long-hub ones in contrast to the male/female ones used in waterproof watches. Note too that while the packaging was supposed to seal the contents from moisture, some packages didn't so as well as others, although in this case it's a very minor matter. 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.
