I used to build submarines in Groton in the mid 80's. Campbell's did have a selection of vintage doubles but I never bothered looking at them cause I couldn't afford them. If they are still there and selling guns I don't know. On the west side of the Thames river just south of Norwich was a shop called Fort Shantok trading post. They came up with some interesting older guns at times. A little further north in Jewet city was a shop in an old mill converted to a mall called Jewet city sports. It was a nice shop. This was a long time ago so I don't know if they are still there but check the phone book. In Rode Island is Robin Hollow out fitters.
