De Lisle carbine
The De Lisle carbine or De Lisle Commando carbine was a British firearm used during World War II that was designed with an integrated suppressor. That, combined with its use of subsonic ammunition, made it extremely quiet in action, possibly one of the quietest firearms ever made.
Few were manufactured as their use was limited to specialist military units.
History.
The weapon was designed as a private venture by William Godfray de Lisle (known as Godfray), an engineer who worked for the Air
propellant gas and the clink of the empty case against any hard surface would produce a noise with each shot. While the carbine was silent, it was not very accurate.
De Lisle's own .22 prototype was given to the National Army Museum in London, but it was subsequently lost and its present whereabouts are unknown. A reproduction of the .45 calibre carbine is manufactured by the American company Valkyrie Arms. Special Interest Arms for a time produced limited quantities of a De Lisle replica which incorporated an improved magazine adapter system that
