Are they 12" Jim ? I have a set in at work that I never use . You can jump the gear to change where they close btw . My set is missing the small clamp on the back end that keeps the beam in the groove . This was one of my first purchases back when I was an apprentice so I know they are old .Dial spins way to freely and the needle is pointed at about 4:30 when closed.
This is .200" per rev.,
6", my bezel clamp is broken.Are they 12" Jim ? I have a set in at work that I never use . You can jump the gear to change where they close btw .
