I saw an ad here locally for some vintage LL Bean Pintails. He also had these and I couldn't resist so I bought a pair along with the Pintails. These came from an old guide that hunted Utah's Bear River Club during the late 50's - 70's. They appear to be black ducks?? But we don't get black ducks around here. They have seen a lot of marsh and bag rub The head connection looks a lot like LL Beans with the washer and holes for different head positions. Any guess who the maker was and what vintage these would be?
