This week, the Lords of War are just outside Houston, Texas. The guys come across great items, including a blunderbuss pistol from the American Revolution, a detailed Bowie knife and a 1907 Winchester, popular with 1920s gangsters. Before the auction, they want to shoot the guns to test their firepower and make sure they're worthy to sell. The guys also get their hands on a piece of body armor from the 1800s. However, reproductions are common, and they must make sure that this is the real deal.
