Lock maker

I need help trying to identify the tomaker of this lock . These marks are the only ones I can find.

Maybe a Goulcher or just a hardware store lock that sold for 25 cents when new.It's called a back action lock because the mechanism lays behind the hammer.

Agree, these plain back-action locks were made by the tens of thousands and there isn’t much to be gained from knowing who made it. Their ultimate destination was always a late percussion inexpensive gun. Still a part of history, sort of like the single shot modern gun that served as an all-rounder in later days.

I just noticed it's a left side lock and may be from a double barreled shotgun.Not all back action locks were low end.I owned a double rifle made by Holland&Holland that was made with very high end back actions During all my time as a lock maker I got NO requests for a back action lock
