Borg & Beck Co.Ltd., Tachbrook Road, Leamington Spa. Dear Sirs, re 10" Long Clutch. for Experimental 3¼ litre engine. Will you please prepare for us two 10" Long C.F. clutches fitted with Blue springs of 110 - 120 lbs, otherwise to spec. BB.460. We estimate that the 10" clutch with these springs (as used in the 11" to spec. BB.471) will be just right for a torque of 170/175 lbs. feet. We would be glad if you would kindly give this a spec. number for future reference. Our official order will follow. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
