 This was a single-engine, single-bay biplane, powered by a 525 hp (391 kW) Panther engine and fitted for wheel or float operation.The sole prototype ("G-ABJM") was certificated on 2 August 1931, and was shipped to Canada for operational trials.While these trials were successful, the Canadian government cut the subsidy for civil aviation and so Canadian Airways was unable to afford new aircraft, so the mailplane was returned to England.
