Sierra and Bolt embedded blanks with WWII RAF Supermarine Spitfire propeller wood and wing cloth. All blanks will come with one COA per blank. COAs are 4" x 6" card stock with foil COA seal. The Rolls-Royce Griffon engine was designed in answer to Royal Naval specifications for an engine capable of generating good power at low altitudes. Concepts for adapting the Spitfire to take the new engine had begun as far back as October 1939; Joseph Smith felt that "The good big 'un will eventually beat the good little 'un." and Ernest Hives of Rolls-Royce thought that the Griffon would be "a second power string for the Spitfire". The first of the Griffon-engined Spitfires flew on 27 November 1941.Although the Griffon-engined Spitfires were never produced in the large numbers of the Merlin-engined variants they were an important part of the Spitfire family, and in their later versions kept the Spitfire at the forefront of piston-engined fighter development. This article describes the Griffon-powered Spitfire variants. The Mk XIX was the last and most successful photographic reconnaissance variant of the Spitfire. It combined features of the Mk XI with the Griffon engine of the Mk XIV. After the first 25 (type 389s) were produced, later aircraft were also fitted with the pressurised cabin of the Mk X and the fuel capacity was increased to 256 gallons, three-and-a-half times that of the original Spitfire This version was the type 390.The first Mk XIXs entered service in May 1944, and by the end of the war the type had virtually replaced the earlier Mk XI. A total of 225 were built with production ceasing in early 1946, but they were used in front line RAF service until April 1954.In 1951, Hainan Island (People's Republic of China) was targeted at the behest of US Naval Intelligence for RAF overflights, using Spitfire PR Mk 19s based at Kai Tak Airport in Hong Kong. The last operational sortie by a Mk 19 was in 1963 when one was used in battle trials against an English Electric Lightning to determine how best a Lightning should engage piston-engined aircraft. This information was needed in case RAF Lightnings might have to engage P-51 Mustangs in the Indonesian conflict of the time. These blanks are embedded with a small piece of the original material from the aircraft. The piece is approximately 1/8” square/round in size. The embedded components are positioned over a starburst silhouette of the aircraft’s outline.
