Newall - 1/4 Dozen Balance Staffs for Gruen caliber 510 movements - New

Newall #2337 Lot of 1/4 Dozen (so that means 3) Inca Balance Staffs for Gruen caliber 510 and perhaps other Gruen calibers, new in envelope. See images for further details. I specialize is hard to find watch parts and have a seemly bottomless supply of Bulova parts (Factory and aftermarket) so I'll usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the lot.
