Burn some rubber with the Pawn Stars when they check out a 1968 Ford Mustang GT fastback. Just like the car driven by Steve McQueen in “Bullitt,” will Rick get into a high-speed chase for this classic muscle? Then, a guy moseys in with an 1858 Smith & Wesson Model 1. The same model used to kill Wild Bill Hickok, will this Old West pistol still pack a punch, or is the seller drawing dead? And later, a man dashes in with a WWII telegraph set. A wireless version often associated with spies, will the guys tap out a good price, or will the seller s bottom line force them to stop?
