PLEASE REFER TO TECHNICAL DEPT. AND QUOTE REFERENCE CMC/MEN IN YOUR REPLY 21st May, 1937. Messrs. Rolls-Royce Limited, Derby. Gentlemen, For the attention of Mr. H.E. West. We are sending you under separate cover and free of charge six special F.E.30x plugs which have been fitted with electrodes made from copper wire and having the shortest possible piece of nickel brazed on to form a firing point. We very much hope that you will be able to test these in comparison with the standard type F.E.30x with a view to ascertaining whether the improved heat conductivity which the copper gives has any noticeable effect on erosion of the central electrode. Yours faithfully, p.p. K.L.G. SPARKING PLUGS LIMITED. Director. | ||
