Da Vinci’s Killer Pistol

The guys are in southern California meeting interesting collectors, testing antique guns, and auctioning amazing items. Sean assesses a 16th century wheellock and then heads to the testing range to see if this ancient mechanism can still light a spark. Hammer examines what seems to be a 16th century german crossbow that could be its owner's key to retirement. Sean inspects what looks like an extremely rare uncut sheet of pre-revolutionary currency.
