Sideplates for the Experts

Interesting that they are both lifter action locks from a relatively close period in time, but different bridge plate designs, with an extra screw in the one Bruce shows.

Edgar, The 4 pin lock Bruce shows is for a higher grade gun. The three pin lock that Brian shows is for lower grade guns up to a grade 3 gun. Both these guns are early so they are referred to as "Dollar Grade" guns.
