| Y6-002b. HS{Lord Ernest Hives - Chair}/Wst.15/JH. 16th April, 1936. Messrs. Lodge Plugs Ltd., Rugby. For the attention of Mr. B. Hopps. Dear Sirs, The CB.14 plugs which you sent to us for test on the new 20/25 engine are unfortunately not suitable, due to the barrel length being too small. Actually we require the length of the barrel including the hexagon to be at least 3/4" and the reach should not exceed 16 m.m. We are therefore returning the 6 plugs to you under seperate cover. Yours faithfully, FOR ROLLS ROYCE LTD. | ||
