Duck and Cover

Overview

Rick and his team take a trip out to a local Las Vegas museum to restore a civil defense air raid siren from 1957. Can they withstand this nuclear restoration, or will they fail to duck and cover? And later, a client brings in a turn-of-the-century, nickel-plated cash register. Will the team ring up this cash counting machine to a pleasing profit, or will this classic calculator crash in financial failure?
