Designed as a private venture, the Type 101 two-seat fighter was powered by a 450hp Bristol Jupiter VI nine cylinder radial. The fuselage was a ply-covered spruce structure and the wings of steel with fabric skinning. Armament comprised two synchronised 7.7mm Vickers guns and a Scarff-mounted Lewis gun. The Type 101, which was first flown on 27 July 1927, offered a relatively high performance, but was rejected by the Air Ministry because of its use of wood. As no other customers presented themselves, the prototype served in the test bed role.

Specification 4/24 issued in 1924 called for a multi-seat twin-engined fighter capable of carrying two of the 37mm Coventry Ordnance Works (COW) cannon. To meet this requirement Frank Barnwell designed the Bagshot, the sole prototype of which was first flown on 15 July 1927. Powered by two 450hp Bristol Jupiter VI engines, the Bagshot had a triangular-section, steel-tube, fabric-covered fuselage and a two-spar, shoulder-mounted wing with a steel primary structure. One 37mm COW gun was carried in an open nose turret and another in a dorsal position, a Scarff-mounted 7.7mm Lewis being carried aft of the latter gun. The crew comprised pilot and two gunners. During flight trials it was discovered that aileron reversal resulting from wing torsional flexibility produced ineffective lateral control, and as it was concluded that the shortcomings of the aircraft could be eradicated only by virtually complete redesign, further flight trials with the Bagshot were abandoned.

In 1927, a lightweight two-seater Brownie G-EBJM, built for the Lympne ultralight trials and much modified as a prospective basic trainer for the Air Ministry, had been allocated to Frank Barnwell as his personal runabout.

Barnwell flew it in all weathers, on one occasion remaining in view for over an hour from Filton as he battled enormous easterly headwinds over the Cotswolds. In March 1928, he crashed it at Farnborough, only yards from his decapitated tree.

Designed by Wilfrid T Reid to meet Air Ministry Specification 3/22 issued in June 1922 for a two-seat fighter, the Bloodhound was flown for the first time at the end of May 1923. Featuring a welded steel-tube fuselage and wooden wings, and powered by a 425hp Bristol Jupiter IV engine, the Bloodhound carried an armament of two synchronised 7.7mm Vickers machine guns and a 7.7mm Lewis gun on a Scarff mounting on the rear cockpit. Three additional Bloodhounds were built to the order of the Air Ministry, the first of these being of all-metal construction and the others having wooden wings and tail. All three were powered by the Jupiter IV, but the engine of the third aircraft was fitted with an RAE supercharger. The three aircraft were delivered to Martlesham and Farnborough between March and September 1925, but no production was undertaken. The original prototype was successively fitted with the Jupiter V and VI, and served primarily as an engine test bed.

The Bristol 72 Racer was designed in 1922, by engineer Wilfrid Thomas Reid. It has a cylindrical monocoque fuselage and retractable landing gear. Of mixed construction wood and metal for the fuselage, the wings fabric covered. Power way provided by a Bristol Jupiter IV of 480 hp.
Controlled by Mr. FC Uwins, it first flew in June 1922. The Racer encountered many problems with instability. Envisaged entering the Aerial Derby of 1922, it was painted red, registered G-EBRD, and given the number 10, it did not take part as it was not ready. With continuing difficulties with development, it was abandoned in 1924 after having flown only 8 times.
