I'm looking for a smooth bore barrel for my Ithaca model 37 featherlite 20 gauge. A gunsmith ruined the one I have. I don't know the age of the gun. It was given to me in the early 70's by my father and he probably bought it in the late 50's. Love the gun, but was told it is unsafe to shoot. All I can find out there is 12 gauge barrels. If anyone knows where I can find a barrel it would help bring a sweet gun back to the fields where it belongs. Thanks!
