Rolls-Royce 1920 Pattern Mk.I
The Rolls Royce Armored Cars arose as a result of a request from the Royal Marines in 1914 to obtain an armored vehicle to defend the Royal Naval Air Services (RNAS) bases. Some parts of a Rolls Royce 40/50 HP Silver Ghost Alpine type passenger car were armored, and months later the Armored Car 1914 Admiralty Turreted Pattern was designed with a rotating turret and a 7.7mm machine gun as armament. After the end of WWI, the “1920 Pattern Mark I” model was developed for the Royal Air Force, followed by the “1920 Mk.1A” type and finally the “1924 Type I” model. They were deployed in Libya and Egypt during 1940, installing Boys 14mm anti-tank rifles instead of machine guns.
