Can anyone identify this?

It just looks like a independent engravers sample plate. It doesn't appear to be Remington.

If they were to sign it or some other way to pin it to the correct person. There are far to many that are not known. Maybe a gunsmith with a little art talent. Could be a plate that some one did in the garage? Maybe the auction could give you some insight on who owned the books? If you could contact them you maybe able to track down who did the plate. Could have been a hobby to the guy who owned the books?
