I finally got all the parts needed, and modified what I could.
-I added a vernier style sight. I have multiple rear sights, including the original leaf/ladder sight and a Lyman tang peep.
-New simple sling I made. Bought period correct mounts. Had to buy a new forend cap to drill a hole.
- Removed Barrel mounted sight and added a blank.
-Made a large lever for ease of use and comfort.
