The Airspeed AS.36, General Aircraft GAL.32 and Percival P.20 were also proposed against specification T.1/37, but not accepted or built.

None of the designs was selected for production orders; it has been suggested[1] that the required performance could not be achieved within the constraints of the Specification.

The undercarriage, tail unit and outer wing panels were adapted from the Parnall Heck 2C.

[4] In trials at the Aeroplane & Armament Experimental Establishment (A&AEE) at Martlesham Heath, it was assessed as pleasant to fly and generally good as a trainer.

It was allocated the serial 3600M[5] and ended its days as an Air Training Corps instructional airframe at Jones' West Monmouth School, Pontypool.
