Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}16/JH.2 27th. June, 1939. Messrs. Borg & Beck Co.Ltd., Tachbrook Road, Leamington Spa. Dear Sirs, Special 10" Clutch Plate. Please make up for experimental work, a 10" driven plate, exactly as standard except for the hub which is to be broached for 1.000 S.A.E. 10 spline, presumably this would use the same broach as for your 8" clutch plate. You could for this one, use the same hub forging as for the 10" and 11" standard plates, and it will not be necessary to reduce the external diameter of the boss. Our official order will follow, it being understood that this special hub will entail an extra charge. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
