I am looking for a balance staff for an 18s KEYSTONE WATCH.
Following approximate dimensions: 5.70 3.07 .71 .91 .68 ? sr sc

S/N 373106
1888/1889
I was hoping that the Keystone watch co used a "standard" staff from one of the other watch co at the time.

Mel it would help if you could crank up a "macro" of the staff in this post. I have had greater luck doing that when I am stuck and start passing the hat around to find one. Below is one of my last "ventures"
