09/30/2009. Remarks by Johan Visschedijk: "Preceded by the purely land-based research prototype Hawker P.1040 (s/n VP401), and the first truly naval prototype (s/n VP413), the pictured VP422 was the last of three prototypes of the naval interceptor designed to Admiralty specification N.7/46. VP422 was first flown by Squadron Leader T.S. Wade on October 17, 1949."
