The gun was purchased new ~1978. When the 2 places I duck hunted went to steel shot in the early 80s, I bought an improved cylinder barrel and this one was retired. Very good condition. Ventilated rib with silver bead. A quick online search showed these priced at $150-$350. A gunsmith could cut the barrel down and add screw in chokes.
Asking $100. Pick up in southwest Hennepin County.
