I got brave and took the locks off my Thomas W. Perkes. Even better is the lock maker is stamped in them as Stanton & Son. They look good to me for being made sometime in the late 1870’s to early 1880’s.

The gun is a 12-b Boss sidelock non-ejector. It was built on the Perkes patent
in 1886.

That is a really gorgeous piece. I hope this picture works of the outside of the lock plate.
