| ORIGINAL TO H.S. FROM R.{Sir Henry Royce} c.c. to C.J. S.J. S E C R E T. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. POWER UNIT. R4/M13. 10. 23. Handwritten: X9310 (struck through) X9770 X9335 (struck through) X9060 We are arranging to modify the EAC. gearbox so that it can be attached to the engine unit. This necessarily causes some considerable alterations & while doing so we have made some definitely better and simpler operating mechanism. We have in hand alterations to the method of supporting the EAC. engine, and cancelling the underframe. We are also carrying out modifications to the valve tappets of EAC, making them parallel instead of taper and fitting down on to collars to avoid expansion differences causing compression of the tappet guides and jamming of the tappets. Tools on the parts affected should be stopped if not completed. R.{Sir Henry Royce} | ||
