The final variant was the HA-1112-M1L Buchon (Pouter), which is a male dove in Spanish. It first flew on 29 March 1954 with a 1,600 hp Rolls-Royce Merlin 500-45 engine and Rotol propeller, both purchased as surplus from the UK. This engine had a chin intake that altered the lines of the Bf 109's airframe. It was an improvised assembly of outdated components but this was appropriate for the intended purpose of controlling Spanish colonial territories in Africa, where more sophisticated technology was both unnecessary and unavailable in isolated Spain at the time. It carried two 20 mm Hispano-Suiza 404/408 cannons and two Oerlikon or Pilatus eight-packs of 80 mm rockets and remained in service until 27 December 1965.
In film
Due to their longevity, Buchons have appeared in several war films masquerading as Bf 109Es and Gs. in movies such as Battle of Britain (alongside CASA 2.111 bombers, a Spanish-built version of the Heinkel He 111), Der Stern von Afrika, Memphis Belle, Dunkirk, and The Tuskegee Airmen. Buchons also played the Bf 109's opposition, the Hawker Hurricane, in one scene in Battle of Britain.
