The parts marked 'x' is only required for future crankcase which are produced with the tappet bores perfectly vertical as shewn on Ex.S.781. The casting to Ex.S.767 can also be used when manufacturing Wraith 111 camshafts. In accordance with memo Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}7/JH.16.6.38. an analysis is to be made of the actual Monikrome" camshaft casting supplied by the Midland Motor Cylinder Co., and a similar material is to be produced by RR.Ltd.
