Built in 1935 as G-ADLS the aircraft has a colourful history including participation in the 1935 Kings Cup Air Race and, after export to Spain in 1936, service in the Spanish Civil War. Following the war the aircraft served with the Spanish Air Force as 30-168 and was later registered EC-CAO and EC-ACB. Withdrawn from use in 1959 and stored in a garage in Zaragoza for 27 years, the aircraft was acquired in 1986 for the fledgling Fundación Infante de Orleans and underwent restoration initially in Spain and later at Booker in the UK, returning to Spain in June 1997.

Painted in its Republican Spanish Civil War markings, this aircraft should be ex G-ADLS. It was discovered in a garage and restored to flying status by the Fundación Infante de Orleans. European Registers Handbook says it is c/n 197, an M-3A Falcon Major, but that machine was allegedly destroyed in 1936.
