To R.{Sir Henry Royce} from EFC. c. to J.{Mr Johnson W.M.} c. to E.{Mr Elliott - Chief Engineer} x 2935 EFC4/T13217. 13th February 1917. X9245 RE POWER CURVE OF "HAWK" ENGINE. Re your memo E2/B9217, asking for Power Curve of "Hawk" Engines, built by Messrs. Brazil Straker, we understand Mr. Bailey has written that firm for some figures, however, I had some figures which were given us by Messrs. Brazil Straker some little time ago, of which I am sending you a copy. These figures practically agree with the power curve of the "Hawk" Engine as experimentally obtained by Mr. Hives, of which I believe, you have a copy, and it will be interesting to see how the new figures which we receive will compare with these.
