Volley gun
The Ribauldequin was a medieval version of the volley gun. It had its barrels set up in parallel. This early version was first employed during the Hundred Years' War by the army of Edward III of England, in 1339. Later on, the late Swiss army employed it.
Liberty Bell (game)
The Liberty Bell was the first variation of the modern mechanical slot machine we see today, originally being referred to as a ""fruit machine"" or ""one-armed bandit"". Created in 1895 by Charles Fey (1862–1944), a car mechanic from San Francisco, the Liberty Bell's popularity set the standard for the modern slot machine; its three-reel model is still used today despite great advances in slot technology over the past several decades. The original Liberty Bell slot machine is currently on display at the Liberty Belle saloon in Reno, Nevada as a historic artifact.
