| X328 To BY.{R.W. Bailey - Chief Engineer} from HDY.{William Hardy} SECRET. HDY.{William Hardy}1/MP.15.6.35. c.c. Gor. E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Ba. RMC. MS/Gry.{Shadwell Grylls} SpectreCodename for Phantom III Gearbox. Existing boxes with ball bearings for the first motion shaft to N. Sch.4405 have a certain amount of waste space by reason of the desire at the initial stage to avoid alteration to the clutch coupling shaft and the front cover of the box. We think that there should now be altered to secure the saving of weight and cost which is possible and accordingly send herewith N. Sch.4537 which shows our suggestions. We should like this scheme included in the specification of the next boxes to be built. HDY.{William Hardy} | ||
