Spitfire Mk XII (A05117) The Mk XII was the first production version of the Spitfire to use the Rolls-Royce Griffon engine. The Griffon was a development of the ‘R’ sprint engine used in the Supermarine Schneider Trophy racing seaplanes of the late 1920s & early 1930s. The low level performance of the Mk XII was very useful when dealing with low level hit & run raids mounted by the Fw 190, & later helped against the V-1, though the mark did not enter mass production.
