FLIGHT. OCTOBER 2, 1931 ANCESTRY: The upper photograph shows one of the Rolls-Royce " Buzzard " engines from which the racing engine was developed. The lower photograph, of the 1931 "R" engine, provides an interesting comparison. some way, from large units like the crankcase and cylindersdown to individual nuts and bolts all over the engine. It is no exaggeration to say that five years of normal de-velopment work would have been required to cover the same amount of ground.It should not be thought that the possibilities of the engine are exhausted. Appreciably greater output than2350 b.h.p. has been obtained from it. Attaining the required standard of reliability would only be a question of time, as most of the known problems involved ai; pretty well understood. In conclusion, examination of Fit. Lt. Boothman's raceengine and Fit. Lt. Stainforth's record engine have shown them to be in absolutely perfect condition ; there were nobroken parts of any description, and from the excellent condition of the bearings it would appear possible toassemble these engines and do the same work c>ver again. 994
