Not a hammerless sidelock, but a back-action lock with DRGM 196172(circa 1905 & more than likely protection for 3 years) on the tumbler/lockwork. I've seen the DRGM stamps many places but I believe this to be a 1st. On a cursory view, anyone have any ideas what makes it novel vs. any other back-action hammergun lock? Somewhat relevant here and only thread that came to mind.
