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.
Webley &amp; Scott
The first Webley production revolver appeared in 1853. Known as the Longspur it was a muzzle-loaded percussion cap and ball pistol. Some consider it to be the finest revolver of its day as it could shoot as fast as the contemporary Colt revolvers and was faster to load. However the hand-made Longspur could not compete in price with mass-produced revolvers such as the Colt, and production never equalled that of Webley's competitors Adams (Deane, Adams & Deane) or Tranter.
