03/31/2012. Remarks by Johan Visschedijk: "The Greyhound tandem two-seat fighter-reconnaissance aircraft was designed by J. Kenworthy as a potential successor to the Bristol Fighter, but the first prototype was not completed until after the Armistice of 1918 owing to difficulties with its 320 hp ABC Dragonfly I nine-cylinder radial engine. Flight testing eventually commenced in May 1919, and three prototypes were built and flown with s/n H4317 to H4319, but no further development was undertaken. Armament comprised two fixed synchronized 0.303 in (7.7 mm) Vickers guns and a single 0.303 in (7.7 mm) Lewis gun on a Scarff ring in the rear cockpit."
