I have two, and have had several other Ethan Allen trapdoor shotguns. Their Damascus varied by grade. In 1869 they offered Fine Stub Twist on their $100 gun, and Fine Laminated on their $150 gun. A special gun, not serial numbered , was made for G.H. Coates, the foreman of the Allen factory. It's barrels are marked Finest Laminated. These guns are interesting in that the bottom half of the breech of the gun, approximately 2 1/2" wide x 3" long x 1" deep, appears to be made from the same piece of "steel" as the barrels.
