I bought an old Model 37 with a Poly Choke on one of the 2 barrels with which it came many years ago. I absolutely loved that thing - back in the lead shot waterfowling days, it accounted for many a long goose, although there was nothing pretty-looking about the thing. Still have it - I just seldom use it anymore, favoring 20 & 28's as I do now. Pattern it & see what it will do.
