My gun has a late English style lock with a small tail. I suspect it was converted to percussion by the original maker, because it had to be removed from the gun to be sure it was converted from flint. I suspect it had a roller frizzen spring, because it has a roller on the mainspring. The brass furniture on my gun is not engraved, but the patchbox, cheek inlay, and sideplate, are. My gun is not signed, but a similarly built gun, with many of the same features, is signed by a gunsmith named Baer. The patchbox, and sheetmetal sideplate are nailed in place with small brass nails.
