YOUR REF Rm{William Robotham - Chief Engineer}11/R.{Sir Henry Royce} 24th July, 1939. W. Robotham Esq., Messrs. Rolls-Royce, Ltd., Derby. Dear Sir, Your letter of Thursday, 20th, has been opened by the writer in the absence of Mr. Blackith, who has now left for a fortnight's holiday. We wish to thank you for the information you have given us regarding the experiments you have made on AC.9 Main Bearings, and note that you definitely do not recommend this use for the material. Although we are supplying far more Big Ends than Main Bearings we have had some very good results at present under the latter conditions, but we are rather following your findings and recommending it more for Big Ends to future customers. Your letter will be kept for Mr. Blackith to deal with further on his return. Yours faithfully, For WELLWORTHY PISTON RINGS LIMITED, L. C. Noble Technical Department. | ||
