Actually I have a friend a few miles away that is a machinist/jack of all trades, that can make about anything he wants out of metal. The tools and things he has is very impressive. He's made parts for my old machinery when I could no longer purchase them because of age. I am sure I can show him a picture of your sight and he will duplicate it. And he is a black powder shooter, so it should interest him a great deal...

thanks for the idea. I have the second sight for the rifle laying around here. Might as well get some use out of it.
