This is a home-built variant of the Pietenpol Air Camper, constructed mostly from wood by Miguel Carrillo Ayala in 1935, using technical drawings he had found in "Popular Mechanics" magazine. It was powered by an engine from a Ford A truck. In February 1936 the aircraft was transported from Carrillo's hometown of Zitácuaro to López airfield near Morelia, where it was first flown by a military pilot. Carrillo himself then flew it back from Morelia to Zitácuaro (100km), and flew it again on 14 May 1936, from Zitácuaro to the military aerodrome Balbuena, near Mexico City (140km). A replica of this aircraft was unveiled on 29 March 2018 in Zitácuaro, at the intersection of Avenida Revolución Norte and Calle Miguel Carrillo Oriente.

Restored to static display condition circa 2012 by the 4th Maintenance Echelon at Santa Lucia AB. It is now a composite airframe, using the fuselage, tail section and other parts of N9623C c/n 108-33967 and various parts of N9877C c/n 108-32420, both of which were previously displayed in the Bosque de San Juan de Aragón park in Mexico City. This aircraft is now falsely painted to resemble B-25J BMM-3503. The real BMM-3503 was c/n 108-47472.
