BESTFIT stems (2) for Elgin Grade 657 Pocket Watch Movements - new in envelope

Two BESTFIT stems for Elgin grade 657 pocket watch movements, BF# 200/1194, new in open envelope. The grade 657 is a LIP caliber R40 based Swiss pocket watch movement.  The package contains two stems even though it says 1/4 doz (which would be 3), presumably one was used which is why the envelope is open. I specialize is hard to find watch parts so I usually have whatever you might need, all watch parts are unconditionally guaranteed and offers are welcome. Images do a suitable job of representing the item.
