In terrible need of T/C part no; 7194 rear sight...

Loaned my gun to a friend and he somehow managed to break the back sight off it. I have called and checked everywhere and I'm absolutely crippled for a muzzleloader without my back sight. if someone on here has one new or used I would sure appreciate it if you would let me know how much and i can send money for it Now. Also if anyone knows of sight of the same style that will work without having to drill or tap anymore holes in the tang I wouldn't care to go that route.

Thanks for your time.
