Today's gun is a real rarity: a flintlock repeater. And, if that's not rare enough for you, it's a King's flintlock repeater—made for Louis XV of France in 1735. This rifle uses the ingenious Lorenzoni system, which is a sort of built-in speed loader. There are two magazines that load through the butt of the gun: one for powder, one for balls. You turned a lever on the left side of the receiver, and it dropped powder first, then a ball into a rotating cylinder, and cocked the hammer. Turning the handle back aligned the chamber with the barrel.
