Firearms with multiple barrels are popular in European hunting. On this week's Curator's Corner, John Popp joins Jim Supica, Director of the National Firearms Museum, for an exhibition of famous and strange combination guns. First on display is a German "vierling," which features two shotgun and two rifle barrels, and was used for hunting a "mixed bag" of game. Supica also demonstrates a Winchester lever-action rifle with a 12-gauge shotgun barrel grafted onto the top, and a Smith & Wesson Russian revolver with a single-shot .22-caliber barrel added to it. Originally aired on 10/22/2009.
