Any info on this old Stevens would be greatly appreciated; age, value, etc. It is a side by side double barrel 12 gauge with side locks and open hammers. Condition is fair, complete and usable but little original finish and many scrapes and scratches. Barrels are 28 inches and appear to be steel and not damascus. One side plate is marked J. Stevens A&T Co. Chicopee Falls, Mass U.S.A. Pats appl'd for. The only other markings on the gun are 41777 stamped inside the forestock, and 249 on the underside of the barrels and inside the frame. The sidelock plates are of a lighter color than the rest of the gun, possibly nickel plated. Thanks in advance for anything you can tell me about this oldie.
