| 86001a. Hs{Lord Ernest Hives - Chair}/Wst.2/MA. 30th October, 1935. Messrs.K.L.G.Sparking Plugs, Ltd., Robinhood Engineering Works, Putney Vale, London, S.W.15. Dear Sirs, We have recently had a failure of one of the new type 843 sparking plugs which we are now testing out on a higher powered 20/25 engine. It occurred to us that the design calls for improvement and we wonder whether you have a similar plug in design characteristics and heat characteristics of the washer type construction, if so we should be glad to receive a sample of this plug for examination and test. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
