An early double barrel with side hammers and damascus barrels might bring $125-$150 as a decorator and a later hammerless boxlock with fluid steel barrels could reach $200+ as a shooter (if deemed safe by an experienced gunsmith). There is no collector interest in them, so they are priced accordingly. These guns were made by Folsom�s subsidiary, Crescent Firearms, Norwich, CT. Shelton � American Gun Co and Knickerbocker were trade names sold by H&D Folsom Sporting Goods of New York City.
