The Scarff ring was a type of machine gun mounting developed during the First World War by Warrant Officer (Gunner) F. W. Scarff of the Admiralty Air Department for use on two-seater aircraft. The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun(s) that allowed an airgunner in an open cockpit to swivel and elevate his weapon (typically one or two Lewis machine guns) around and easily fire in any direction. It was simple, rugged, and gave its operator an excellent field of fire. It was widely adapted and copied for other airforces.
