My Model 12-A has a flip-up tang site (2 screws) and a front sight. The rear slot is empty. I've seen some 12's with all three sights. Is there a "correct" configuration?
Is the sight a Lyman R-12? Next: Should the sight have an eyepiece of some sort or a simple peep with a slight elevation adjuster? Y'think this sight is original or were most of them added-on?
Thanks again for your attention!
