01/31/2011. Remarks by Johan Visschedijk: "A private venture intended to compete with the Sopwith Snipe, the Osprey was of wooden construction with fabric skinning and was powered by a 230 hp Bentley B.R.2 nine-cylinder rotary engine. Armament comprised two fixed and synchronized 0.303 in (7.7 mm) Vickers machineguns and one semi-free Lewis gun of similar caliber on the rear spanwise member of the middle-wing centre section. The Osprey was flown for the first time in February 1918, but performance proved to be inferior to that of the Snipe, and construction of second and third prototypes was abandoned.
The Osprey's were serialed X15 to X17 in the Licensed Series."
