Ed,
I recently purchased my third Ross, two sporters and a Mark IIIB. The IIIB has a different rear sight, somewhat of a triangle and the small lever that is activated to unlock the inside peep sight allowing it to slide up and down is gone. So the peep just bounces around. Does anyone happen to have another of these sights that I could purchase? If I had the lever and spring it could be repaired. Thanks for the help.
