<p>c/n 4426.
Built 1939.
Only three M.18s were built and this was the only Mk.II. It had the fin moved forward on the fuselage and was powered by a 150hp Blackburn Cirrus Major III. It was allocated the British military serial HM545 when used for evaluation trials but despite having better handling than the Magister then in service it was believed to lack robustness and was not ordered. 
On display in the Civil Aviation Hangar at the National Museum of Flight (part of National Museums Scotland).
