Rolls-Royce, Ltd., Derby. Dear Mr. Robotham, [Handwritten annotation: Your ref Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 1/MJ.] As promised in my last letter, we have now made up some L.K.S. plugs with the increased length of barrel which you considered desirable. The L.K.S.6, which is similar in other respects to those which you have been testing, now has the barrel lengthened to .6", while the L.K.S.5 has a barrel of .85". I shall be very grateful if you will examine these and let me have your criticism of them. Yours faithfully, [Signature: A. {Mr Adams} Carington] Director. | ||
