| [Stamped] ORIGINAL [Stamped] RECEIVED I II III MAY HS.{Lord Ernest Hives - Chair} (E.{Mr Elliott - Chief Engineer}) FROM R.{Sir Henry Royce} DATE [struck through] C. to SG.{Arthur F. Sidgreaves - MD} WORS BY.{R.W. Bailey - Chief Engineer} [partially struck through] R2/M8.5.31. [Handwritten] 84024. FUTURE ENGINES (CAR & AERO)----- INCLUDING J.3., P.V., & P. 3. For first class luxury cars we need more than 6 cyls., which cannot be considered prohibitive on the ground of cost because there are plenty of lower priced cars with 8 and 12 cyls. It is necessary to avoid depending entirely upon soft rubber vibration insulation. [Handwritten in margin] out-turn Also it is absolutely necessary to get a stable front [word 'and' is struck through] end [handwritten 'with-' above 'end'] [handwritten 'Less' is circled above 'vibrations'] vibrations. The ideal engine is of 12 cyl.s. which we are trying first on the Phantom. R.{Sir Henry Royce} | ||
