Two prototypes were ordered, identical apart from the vertical tail surfaces. For manufacturer's trials the first prototype was completed as a landplane and the second prototype as a twin-float seaplane, the first flying in December 1927 and the second in April 1928. The second prototype was also fitted with a land undercarriage in June 1928. Armament was two 7.7mm Vickers machine guns synchronised to fire through the propeller disc. Performance during evaluation at Martlesham was unspectacular and no production order was placed.
