Corgi Supermarine Spitfire MkIXc

Desperate to ensure the Spitfire maintained its ongoing combat effectiveness, designers at the Vickers Supermarine Company were almost constantly engaged in modifying, upgrading and improving their famous fighter throughout the Second World War, however, during that time, there were occasions when unexpected Luftwaffe advancements called upon their flexibility and ingenuity. With a significant new variant of the Spitfire at the advanced stages of development, the introduction of a capable new German fighter aircraft in the skies over occupied Europe caused great concern amongst RAF officials, who were now losing Spitfires at an alarming rate and needed an immediate response. With the proposed squadron introduction of the new Spitfire Mk.VIII variant still some months away, Supermarine designers had the idea of mating the intended new powerplant for this aircraft, the Rolls Royce Merlin 60 series engine, with existing Spitfire Mk.V airframes already on the production line, a temporary solution which might just buy them the time they needed.The idea was given official approval and the RAF's Emergency Interim Fighter Programme got underway, with the new variant given the designation Spitfire IX, a stop-gap solution which would actually prove to be something of a fighting thoroughbred. In actual fact, this undertaking was not without several rather significant challenges for the team at Supermarine to overcome and but for the severity of the situation in the skies over Europe, may have actually been regarded as too problematic. Attaching the powerful new variant of the Merlin engine to existing Spitfire airframes was fraught with challenges, as the new unit was larger, wider and featured a redesigned rear section, all of which made this far from a simple exchange of engines. Supermarine technicians had to remove all existing systems and connections, design a new engine mount, then replace all fittings with newly upgraded components, all of which were essentially hand built. In fact, it could be argued that many of the first Spitfire Mk.IX fighters were hand built, with each one having an incredible number of man hours devoted to their p
