| X.3468 To By.{R.W. Bailey - Chief Engineer} from R.{Sir Henry Royce} c. to CJ. c. to Hs.{Lord Ernest Hives - Chair} R9/G27.7.20. X.3468 RE ENGINE UNDERSHILED - CHASSIS 73TW, 49CW & 7FW SWEDEN. With reference to By1/P20720, will Mr. Hives let us know if it is necessary to continue to use louvred undershields Do they lessen the air pressure under the bonnet, and effective-ly make any difference to the temperature of the floor boards? I have reason to believe that they are not worth their defects. We should pay a reasonable claim to Mr. Rosenlew if we admit we are wrong. R.{Sir Henry Royce} | ||
