Avro 604
Antelope J9183
(c/n
The
Antelope was a day bomber built to the same spec (12/26) as the Hawker
Hart and Fairey
Fox. The Avro design
was not selected and consequently only the prototype was
built. Follow-
ing testing at Martlesham Heath,
the airframe was used as a test bed for various iterations of Rolls
Royce Kestrel engine. Based on the
chin radiator in the photograph above the aircraft appears to
be fitted with the original 480 hp
Rolls-Royce F.XIB engine.
