Girandoni Repeating Air Rifle
The Girandoni Repeating Air Rifle was designed and produced in the 18th century within Italy, and used air in order to propel traditional bullets. The unusually-shaped stock doubled as a reservoir for the aforementioned air.
The LeMat Revolver was also known as the “grapeshot revolver,” as it could transform from a nine-shot revolver into a single-shot shotgun by the user within a moment. It was adopted by the Confederate Army during the US Civil War.
