Thanks rp, I bought it for 100 bucks at a pawn shop, locks extremely tight, looks not to have been used much at all, no proof marks, just the numbers and twin ports arms co. stamped on both sides, I am sure it was made for the duluth Minnisota market by some maker, probably will never know. loaded a shell with just a primer and it fired them with no problems..so may take it out on some dove with some 21/2 shells....
