This must be made right across the boarder perhaps in the Ruhr. Just look at the back of the action and how beautifuly wood carving compliments that underlever. Thuringian "beaver" would cut much deeper into that wood. I see lot of gut French influence in that piece.
Morris Hallowell is listing couple of Charlins with Petrik closure, but they worth only about half of his asking price. He even has small French flag next to word translation.
