AND QUOTE REFERENCE CMC/MEN IN YOUR REPLY WST 15th July, 1936. Messrs. Rolls-Royce, Ltd., Derby. Gentlemen, For the attention of Mr. West - Hs{Lord Ernest Hives - Chair}/Wst.14/JH. In reply to your letter of July 9th on the subject of trouble with type 850 sparking plugs in one Bentley car, it is almost impossible for us to give an opinion on this without inspecting the plugs. We note that they have been used for "pottering about" in London and, at first sight, it would appear that this has probably led to sooting up of the insulator. If you did not examine them immediately after the period when they had been missing it is possible that they have been used for a short time at high speed and that this had cleaned them and left only the grey deposit which you found. As you can find nothing wrong with the plugs themselves and as we know that normally they give regular firing, it is hard to imagine that anything else, except soot resulting from slow running, can have caused this trouble. Yours faithfully, p.p. K.L.G. SPARKING PLUGS LIMITED. [Signature] Director. | ||
