C & E Marshall balance staff E8935 for Elgin 12s No. 4191C P09 DR

C & E Marshall cataloged balance staff E8935 for Elgin 12s movements, DR, Pivot 09, Factory No. 4191C, Refill 85, new in envelope. See images for further details. This is a Transferred by Customer staff meaning a past watchmaker took it from anther system and added into their Marshall inventory so as to not have to look in several places.  I likely have several of these so the one you get may differ very slightly from the images. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
