Subsequently, a prototype was ordered for evaluation, but the other design did not gain official backing. Nevertheless, Bristol considered it promising enough to build a prototype to be entered for the F.9/26 trials as a private venture, powered by a

Bristol preferred to use their own engine designs, but was revived in 1926 when Barnwell started work on a design, designated the Bristol 102, to meet either F.9/26 for a day-and-night fighter or N.21/26 for a shipborne

Mercury was not yet available, and the aircraft was not delivered to Martlesham Heath for evaluation until March 1929. The Bullpup prototype was subsequently fitted with a Jupiter F type head with twin compensator rods for the penthouse heads. Trials with this engine were
