Rick tries to refurbish a 1950's coke machine into a modernized collector's item. Will his plan quench his thirst or fizzle out and go flat? Meanwhile, Corey is offered an old pirate favorite: an 18th Century flintlock pistol. But before he can pull the trigger he'll need to authenticate it. In addition, the Pawn Stars get a chance to buy a 1941 Philco Radio. Will they dial in a deal, or be stuck searching through the static?
