| To RHC.{R. H. Coverley - Production Engineer} x312 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}15/KW. 21.3.35. SpectreCodename for Phantom III Clutch. We wish to add a considerable amount of inertia to the single plate clutch. The easiest place to do this is on the side of the flywheel nearest the front of the engine. Will you please by means of plasticene find out how much material can be added here without preventing the crankshaft and flywheel being assembled in the engine as one unit.
