I hoped with 152 veiws, someone might have an opinion. The raised rib below the cheekpiece seemed like it might be a telling feature. I dont remember seeing this before, but I am certainly a novice at collecting and building. I enjoy researching the history on the guns I own and have looked through all the books that I have without anything jumping out at me besides the Tryon connection. Just bumping this back to the top for another try, Thanks, Roland
