Is that a "Roller" lock signed on the outside?
Maybe it's one of mine.In the long gone past I made a few square tail locks copied
from a gun made in Western Ohio but do not recall marking them externally but
that style of metal stencil was at one time a common hardware store item and I still
use mine a lot. HH is right,an odd breeding of barrel,lock and trigger by an obscure maker.

thinking this is bogus.
