| X4050. HS{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}4/AD. November 10th, 1931. MR. Healey, The Dunlop Rubber Co.Ltd. Fort Dunlop, Erdington, Birmingham. Dear Mr. Healey, With reference to your letter ref. W.D.B. of the 6th inst. I much regret that I cannot establish a single case where it was proved that tyre noise was materially reduced by the shape of the wing, nor do I know of the car you mention illustrated in "The Motor". The subject appears to be like so many others, mainly conjecture without experimental proof. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
