The history of this aircraft is unclear but it is certainly not a genuine Spanish air force Storch. The reported construction number belongs to a French-built MS.500, registered F-BBAS between 1959 and 1966. The Museo del Aire says that it is a Fi 156A obtained from the Autotechnik Museum in Germany. Other sources say it is a Fi 156C-2, with Scramble adding it is a composite airframe, and the c/n is given by others as 2027/2.
