i have got a 12 ga. auto shotgun. it says on it Breda Brescia, has a patent number and says distributed from a town in Conn. it has long barrel with venting near then end apparently to cut down on recoil. it seems to be a heavy gun to me. it is a real good looking gun. it is hard to get information since there does not appear to be a model number. any of you know anything about this gun?
