One of the last HA-1112-M1L Buchón, repainted to represent a German Bf109, with Luftwaffe markings, and still flying. It can be recognized by the exhaust pipes at the top of the nose, like the Spitfire
The Hispano Aviación HA-1109 and HA-1112 were license-built versions of the Messerschmitt Bf 109G-2 developed in Spain during and after WWII.

Design and development

The Spanish government in 1942 arranged a manufacturing licence with Messerschmitt AG to build the Bf 109G-2, with DB605A engines, propellers, instruments, and weapons to be supplied from Germany. This proved impossible, as Germany was incapable of meeting her own needs, let alone Spain's; in the event, only twenty-five airframes (minus their tails) and not even half the necessary drawings were delivered.[1]
As a result, Hispano substituted the 1,300 hp Hispano-Suiza 12Z-89 engine, which flew at Barcelona in 1944, while the first HA-1109-J1L made its maiden flight 2 March 1945 at Seville, using a VDM prop and lash-up engine mounting.[2] The other twenty-four airframes were flown during 1947-9 with Escher-Wyss props, but never became operational.
A developed version, with an improved installation for the Hispano-Suiza 12Z-17 engine, appeared in May 1951 as the HA-1112-K1L.[2] Fitted with a three bladed DH Hydromatic[2] propeller, it was nicknamed Tripala ("three blades"). Its armament consisted of one or two 12.7mm Breda machineguns[2] and Pilatus eight-packs of 80mm rockets.
It first flew in 1951, and although 200 units were planned, only 65 were ever built. The Hispano engine was an upright V12 in contrast to the inverted V12 Daimler-Benz DB 601 & 605 engines used in the Bf 109. Being however of compact design, it fitted the airframe of the Me109 well, representing it in the German Film "Star of Africa". In the original design, an asymmetric vertical fin with an airfoiled profile had been introduced starting with the Bf 109F to produce a slight left movement of the tail, which counteracted the left-side torque reaction from the Daimler-Benz engine's counterclockwise rotation. Since this was left unchanged in the Buchón, and the Hispano V12 powered a clockwise-turning propeller, the combination of the airfoiled fin and the clockwise-turning propeller created a hard-to-counteract right swing on takeoff, since the fin and the propeller essentially worked in the same direction.
A second version, the HA-1110-K1L, was a two-place tandem trainer model.[2]

HA-1112-M1L

The final variant was the HA-1112-M1L Buchón (Pouter), which is both a male dove or a pelican in Spanish. It first flew 29 March 1954. The 1112-M1L was equipped with the 1,600 hp Rolls-Royce Merlin 500-45[3] surplus bargain engine and Rotol propeller.[3] This clumsy though reliable "power-egg" WW2 bomber engine had a deep chin intake, that ruined the sleek lines of the Me109 visually. As such, this plane was an improvised assembly of outdated components for the specific purpose of controlling Spanish colonial territories in Africa where a higher level of technology was unnecessary, and moreover not available in isolated Spain at the time. Its armament consisted of two 20 mm Hispano-Suiza 404/408 cannons and two Oerlikon or Pilatus eight-packs of 80 mm rockets. It remained in service until 27 December 1965.
HA-1112-M1Ls remained in flying condition until the mid-1960s. This made them available for theatrical use, disguised as Bf 109Es and Gs in movies like Battle of Britain, Memphis Belle, and The Tuskegee Airmen. Remarkably, Buchons also played the Bf 109's opposition, the Hawker Hurricane, in one scene in Battle of Britain.
Privately owned Hispano HA-1112-M1L Buchon rebuilt to an Me 109F in Germany with a (probably Swedish) Daimler-Benz 605 engine and Luftwaffe colour scheme at RIAT. (2010).
It has crashed two times in its career and has been rebuilt each time.
