| x336 To Hs{Lord Ernest Hives - Chair}/Mths.{Reg Matthews} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/KW.6.4.36. We ought to be looking into the question of getting some high unit pressure rings for the SpectreCodename for Phantom III in case we run into overoiling. Will you please get some figures on the existing rings and, as a result of the figures you get on the Bentley, order what you think would be desirable for the SpectreCodename for Phantom III.
