Pawn Stars - Season 4 Episode 28

The Pawn Stars are off to the races when a guy brings in a 2000 Porsche Carrera engine that has been recovered from a junkyard. Can this deal go through firing on all cylinders, or will the engine's questionable history make the negotiation run out of gas? Then, the guys pace themselves for a showdown when a seller brings in an early 19th century dueling pistol. Just half of the original two-gun set, will they drop some Hamiltons on this rare piece, or will they misfire and have to run for cover? And later, Rick is ready to rock when a hat once owned by Lynyrd Skynyrd front man Ronnie Van Zant comes into the shop. Will he give a sweet home to this piece of music history, or will the seller fly free and keep the hat for himself?
