Unarmed Sopwith Pup B2192, built by Whitehead Aircraft Co Ltd, Richmond, Surrey, was the personal aircraft of Major E. L. Foot, MC, of the Gosport School of Special Flying. It was in this aircraft that Maj Foot led a “circus” of Pups in formation aerobatics over the RFC Training Camp at Beaulieu, Hants, on September 7, 1917. Its engine is a 100 h.p. Gnome Monosoupape rotary, with extra cooling louvres in the top of the cowling. The tail of Camel B5157 can be seen behind.

A de Havilland D.H.4 day bomber, A76?? Effie, from the batch A7401-A8089 built by the Aircraft Manufacturing Co Ltd at Hendon. This example has the 250 h.p. Rolls-Royce Eagle engine, and has the later fuel system using two wind-driven pumps on the fuselage behind the pilot, which replaced the original pressurised system.

Bristol Scout C 3051, built by the British & Colonial Aeroplane Co, was one of the batch 3013-3062 ordered by the Admiralty on June 6, 1915, featuring tailplanes of increased span and area. This machine was not delivered until mid-February 1916, owing to a shortage of 80 h.p. Gnome engines. It is completely covered - even down to its struts and wheel covers - with an unconventional two-colour "splinter" camouflage scheme, and has a large, faired head-rest for the pilot. Another US serviceman is visible behind it.

Handley Page O/400 D9689, built in Lincoln by Clayton & Shuttleworth Ltd, surrounded by both RAF and United States Air Service personnel (note hats of the latter). Power was provided by a pair of 360 h.p. Rolls-Royce Eagle VIIIs

Bristol F.2B Fighter A7195 was a Series I example, with the 190 h.p. Rolls-Royce Falcon I engine. It was from the first production batch of 200 aircraft assembled at Brislington by the British & Colonial Aeroplane Co Ltd. Delivery of these aircraft began on April 13, 1917, the first squadrons to be equipped with the type being Nos 48 and 11.

A9812 was the last of a batch of 50 Avro 504A/J trainers built by S. E. Saunders Ltd at East Cowes, Isle of Wight. It was probably completed as a 504J, with the 100 h.p. Gnome Monosoupape in place of the 80 h.p. Gnome of the 504A. The two variants were externally identical.
