| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to CJ. Wor.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} EP.{G. Eric Platford - Chief Quality Engineer} X.4247. E1/M31.5.22. GOSHAWK 11 GEARBOX X.4247. We send you herewith drawing No.LeC.1591 shewing a new pair of gears for altering the ratio of the second speed from .627 to .584. Mr.Royce would like one pair of gears only tried for the purpose of testing this new ration. During a recent journey he made on the Goshawk, he was inclined to think that better results might be obtained with the second gear slightly lower so as to get more revs. out of the engine.
