| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to CJ. X.1692 X.3317 X3317 R1/C9.6.21. RE HORSE POWER RECORDS. With reference to your memo Hs{Lord Ernest Hives - Chair}1/LG3.6.21, the confusion has been that they are both dynamometers, one R.W. dynamometer and the other Test Plate dynamometer. Let us say in future, R.W.HP. and T.P. HP. dropping the word dynamometer as much as possible. R.{Sir Henry Royce} 1804 R R.{Sir Henry Royce} 235B (100T) (S.H. 198.10-12-20) G 2948 | ||
