| To RHC.{R. H. Coverley - Production Engineer} x328 Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}11/KW.2.9.35. SpectreCodename for Phantom III Gearbox. In our memo. Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}5/KW.28.8.35, we asked you to increase the angle of the top and third synchromesh cams from 47½° to 52½°, and sketched the way in which we wanted this done. Will you please increase the 2nd speed synchromesh angle in the same way from 50° to 55°. This, of course, cannot now be done on SpectreCodename for Phantom III II, but we should like it to be done on SpectreCodename for Phantom III I at the same time as the top and 3rd angles are changed. Will you please detail this and either construct new pieces or alter existing ones. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
