hello piced up a nice ithaca 37 20ga.I need a smoothbore rifle sight barrel for it any help appreciated

Go over to shotgunworld.com and find the Ithaca forum, post your question there. I believe a guy named Les Hovencamp posts there, he was a head gunsmith for Ithaca and now has his own business, primarily working on Ithacas. Diamond Gunsmithing I believe is his business' name, somewhere in New York. I have a 37 made in 1948, I was going to have him fit a barrel to it so I didn't have to use the full choked barrel that came with it, but found I hit so good even with full choke that it wasn't worth the money for me.

thanx i think i've heard of him i'll try to find him
