Stevens SxS question
First off, Hello everyone out there. I am brand new to this board and I need some assistance on a Stevens Shotgun. I just bid on and won a Stevens SxS, 12 ga shotgun. It is a model 311E and the serial is A5291XX. I would like to find out what year this shotgun was manufactured. I am trying to find out if it is old enough to be considered C&R. Any help you can offer would be greatly appreciated.
