Saw a Browning A5 at a garage sale.The gun is a 12g magnum,serial number dates it as a 1963.It has the 32" full choke barrel,not vented.Wood and bluing was very nice.Has the rubber Browning recoil pad.Shoots the 3"shell.I would rate the gun at75-80%.What are these worth?Is the 32" barrel worth a little more? Thanks
