The Puckle gun (also known as the defence gun) was a primitive crew-served, manually-operated flintlock[1] revolver patented in 1718 by James Puckle (1667–1724), a British inventor, lawyer and writer. It was one of the earliest weapons to be referred to as a "machine gun", being called such in a 1722 shipping manifest,[2] though its operation does not match the modern use of the term. It was never used during any combat operation or war.[3][4] Production was highly limited and may have been as few as two guns.
