I have an Ithaca Model 37 Featherlight in 20 ga that my father bought in the 1970s. It was used very little by him. I inherited it, and it has been in storage for 30 years. It is in remarkably good shape. I took it out to shoot trap with my son after Christmas, and it functioned well for about 50 rounds, but now needs some work. I live in Floyds Knobs in Southern Indiana and am looking for some recommendations for a gunsmith who can help me out. This gun has sentimental value to me. I'd like to get it back in functioning condition, use it only sparingly, if at all, and pass it on to my son. Any rec's?
