Highly recommended again is Tony Buttlers "British Secret Projects, Jetfighters
since 1950".
According to this great source, the AW.165 was an all-weather interceptor,
powered by two Sapphire Sa.7 engines, maximum speed would have been
about Mach 1.1 to 1.2 .
My drawing was based on the 3-view and the artist impression shown in BSP,
the landing gear is based on the description only, so this detail should be regarded
with some scepticism.
