Dear Sirs, As arranged during your recent visit to us, we enclose an arrangement drawing showing the cylinder head and cylinder block of our 25 H.P. unit, for the attention of Mr. Cross. Although there is no drive available for the rotary valve shaft this part of the job could be dealt with by us later, as we realise that the main problem is whether Mr. Cross will be able to layout a scheme to adapt the rotary valve to this engine without having to involve any alterations to the existing crank-case pattern. The booklet and information have been passed on to the Aero Section for their inspection. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
