HAWKER HART TRAINER. Painted bright orange overall, this Hawker Hart Trainer K6448 was an R.A.F.V.R. visitor at the 1937 Biggin Hill display in connection with the Air League - sponsored Empire Air Day celebrations. Identification of "legitimate" Hart Trainers is not simple, for a number of earlier Hart variants was modified to Hart Trainer standard - to Air Ministry Specifications T.8/32 and T.8/35. In the Hart Trainer the rear cockpit has an unbroken line, whereas the military variants had provision for a gun mounting. The tail skid was replaced by a tailwheel, and the exhaust pipes on the 550-h.p. Rolls-Royce Kestrel X (or 515-h.p. Kestrel Ib) were angled down under the lower mainplanes in the manner of the Fleet Air Arm's Osprey carrier-borne, two-seat fighter.
AVRO 566 AVENGER. The Avenger was one of the series of prototype single-seat fighter biplanes produced between the two World Wars. It first appeared in 1926, powered by a 525-h.p. Napier Lion VIII engine, which was later substituted by a 570-h.p. Lion XI. With the latter engine the speed was 180 m.p.h., and the rate of climb 2,100 ft/min. The fuselage was a metal monocoque structure, and the design allowed for the fitting of wings of different areas for operation at different heights and in various categories. In this picture the Avenger is seen starting from Hendon in the King's Cup Air Race on 20th July 1928, flown by J. ("Mutt") Summers. Dimensions: span 28 ft. 0 in.; length 25 ft. 6 in. Weight loaded 3,414 lb.
REGGIANE P.32bis. The Reggiane P.32 has a complex design history. Illustrated for the first time is the initial bomber variant which commenced life as the Caproni Ca 405C Procellaria high-performance aircraft built by the Officini Meccaniche "Reggiane' S.A. of Reggio for record-breaking purposes.
Re-designated P.32-I, the design was produced in small numbers from 1937 onwards, but the P.32-I never saw operational service with the Regia Aeronautica. A second version, the P.32-II which featured a shorter fuselage and reshaped tail surfaces.
GRAHAME-WHlTE MILITARY BIPLANE. This little-known biplane, powered by a 100-h.p. Monosoupape Gnome rotary engine, appeared in 1914 and was a conversion of the floatplane produced to take part in the Circuit of Britain seaplane race. It was designed by Mr.J.D.North, then chief designer to the Grahame-White Aviation Company at Hendon. The seaplane was damaged during a practice flight, and as the 1914-18 War prevented the seaplane race from being flown, it was rebuilt as a military landplane. It was not in fact adopted for production. Dimensions: span 27ft 10 in.; length 26 ft.6 in. Max.speed 80 m.p.h.; landing speed 42 m.p.h.
