A Hispano Aviación HA-1112 (c/n 156 C.4K-87 (D-FMBB), "FM+BB"), a license-built Messerschmitt Bf 109 G-2. Rebuilt by the EADS/Messerschmitt Foundation, Germany with a Daimler-Benz DB 605 engine as a G-6. The paint scheme is missing the Swastika, due to current German laws.
Information from Wikipedia
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.
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. 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-1109-K1L. Fitted with a three bladed DH Hydromatic propeller, it was nicknamed Tripala (‘three blades’). Its armament consisted of one or two 12.7mm Breda machineguns and Pilatus eight-packs of 80mm rockets.
It first flew in 1951, and although 200 units were planned, only 65 were ever built. The aircraft in the upper picture was posted to Tablada, Morón, Torrejón and León. It was retired from service in 1955. On 6 May 1971 it was placed in the Museo del Aire.
A second version, the HA-1110-K1L, was a two-place tandem trainer model.
The final variant was the HA-1112-M1L Buchon (literally, ‘big throat’), 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 engine and Rotol propeller. This engine required the addition of a deep chin intake, whence the name Buchón. 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.
Since the HA-1112-M1L remained in flying condition until the mid-1960s, it allowed them to later be used for theatrical purposes, disguised as Emils and Gustavs (See Messerschmitt Bf 109: Developments after World War Two) in movies like ‘Battle of Britain’, ‘Memphis Belle’, and ‘Tuskegee Airmen’. Remarkably, Buchons also played the Bf 109′s opposition, the Hawker Hurricane, in one scene in ‘Battle of Britain’.
