Robotham Esq., Messrs. Rolls-Royce Ltd., DERBY. Dear Mr. Robotham, You will possibly remember that I mentioned to you we were trying to design a Centrifugal type Supercharger for the 500 h.p. engine, and we are having a little difficulty in obtaining information on which to work. You were kind enough to mention that you would have this checked for us. I enclose drawing with suggested arrangement. Perhaps you would be good enough to have this criticised and suggest the necessary modifications in light of your peoples vast experience on such matters. This information would be appreciated at an early date. Kind regards, Yours sincerely., for F.M. ASPIN & CO. LTD., [Signature] MANAGING DIRECTOR. | ||
