E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} RHC.{R. H. Coverley - Production Engineer} SpectreCodename for Phantom III with Conventional Front Axle. Herewith is N. Sch.4417 shewing a provision on the camshaft bearing for an oil drain and shield, should it be necessary to apply centralised chassis lubrication to this bearing. We have also shewn a more powerful pull off spring which we expect may be required on account of the system of brake operation on the axle. N.Sch.4417 herewith. Da.{Bernard Day - Chassis Design} | ||
