Bristol B.133


Another private venture design for the F.7/30 competition, the Type 133 single-seat fighter featured a forward fuselage of girder-type construction, a monocoque rear fuselage and Alclad stressed skinning. Powered by a Bristol Mercury VIS.2 rated at 620hp for take-off and carrying an armament of two synchronised 7.7mm Vickers guns in the fuselage and a Lewis gun of similar calibre mounted above each mainwheel housing, the Type 133 flew for the first time on 8 June 1934.

After completing a considerable amount of flying, on 8 March 1935 the prototype got into a flat spin and the engine stopped, the pilot baling out and the aircraft being destroyed. No further development was undertaken.
