| To RHC.{R. H. Coverley - Production Engineer} +307 Hs{Lord Ernest Hives - Chair}/Smth.4/KW.9.2.35. SpectreCodename for Phantom III Camshaft E.86371. We wish to try a timing which is 6° more advanced than the present one. One tooth on the camshaft wheel is worth 12°, so we shall have to provide an alternative keyway in the shaft. Will you make us a camshaft to E.86371, but with two keyways as on Hs.{Lord Ernest Hives - Chair}1768. Hs{Lord Ernest Hives - Chair}/Smth. | ||
