| x4425Q Hs{Lord Ernest Hives - Chair}/Wst.1/MA. 21st July, 1934. Messrs.Lodge Plugs Ltd., Rugby. K401 Plugs for Bentley Chassis. Dear Sirs, We have now given these plugs a thorough trial on one of our Bentley test chassis under ordinary road conditions in England. Our conclusion was that they were definitely running too hot. This is particularly noticeable at high speeds, the power falling away in a marked manner. We found we could always regain this loss of power at high speeds by changing to standard plugs. We are therefore returning these plugs to you under separate cover for your examination. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
