| TELEPHONE No 1432 HOLBORN. TELEGRAMS: CRESSY, WESTCENT, LONDON. c/o Cresswell Brothers 18 & 19, Red Lion Square, London, 27th April 1931. W.C.1. The Managing Director, Rolls-Royce Ltd. 14 Conduit Str Dear Sir, The latest in the way of Patents - taken out on the Continent & protected here is of a far-reaching effect. It consists of a small attachment to the interior of the motor & saves from 25% to 50% of the Petrol Consumption, & on the top of that it increases the running power by another about 10%. It appears that there are not these mere assertions, but facts, because the apparatus has frequently practically been tested = giving the results indicated. I have at the moment nothing to sell. The sole object in my writing to you is to invite you to try this little invention for yourselves on your cars & then favour me with your considered judgment. It will cost you nothing beyond the slight trouble the experiment might justify it. You can imagine the enormous difference it would make on the consumption of the commodity if the apparatus should get into general use. Yours faithfully D.{John DeLooze - Company Secretary} Henderson | ||
