| A clean single-seat biplane designed by F A Bumpus
and B A Duncan as a private venture to meet the requirements
of Specifications F.9/26 and N.21/26, the F.1
could accept a variety of air-cooled and water-cooled
engines in the 450-600hp range. The base aircraft was
assigned the name Blackcock but it was intended to
allocate individual names to variants as and when
built. The F.1 was of all-metal construction and primarily
fabric covered, and armament was intended to
comprise two 7.7mm Vickers guns in the
fuselage. The prototype, powered by a 446hp Armstrong
Siddeley Jaguar VI 14-cylinder two-row radial,
carried no armament and was flown for the first time on
14 November 1927. Built to a Turkish government contract,
the prototype was allocated the name Turcock
but was destroyed in an accident on 23 January 1928,
no further development being undertaken.
