| To RHC.{R. H. Coverley - Production Engineer} X30D Hs{Lord Ernest Hives - Chair}/Smth.28/KW.19.3.35. SpectreCodename for Phantom III Dynamo Drive. The dynamo pinion bearing load is quite small and we think we ought to be able to get away with gravity fed lubrication if we modify the oil grooves on the spindle. Will you please build up SpectreCodename for Phantom III unit No. 5 with the modified spindle Hs.{Lord Ernest Hives - Chair}1843. This has four spiral grooves instead of two straight ones.
