Bestfit Balance Staffs (2) for General caliber 800 movements - New

TWO Bestfit System 100 Balance Staffs #350 for General caliber 800 movements and perhaps others as well, new in open envelope. See images for further details. These originally came packaged as 1/4 doz but there are only two in the envelope.  I specialize in hard to find parts so I'll usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.
