For the attention of Mr. Blackith. Dear Sirs, We had an enquiry in October of last year from Panhard and Levassor of Paris regarding AC.9 bearings. Correspondence at the time got to the stage where drawings of crank and lubrication system were to follow. Has any further development taken place at your end concerning this firm ? Turning to another subject; what do you consider is the best method and instrument to adopt in connection with the measurement of cylinder borewear ? Yours faithfully, for ROLLS-ROYCE LTD. | ||
