| X3398 TO Mr.C. & F.H. from R.{Sir Henry Royce} C. to Mr. Ev.{Ivan Evernden - coachwork} Hy.{Tom Haldenby - Plant Engineer} EP.{G. Eric Platford - Chief Quality Engineer} Hs.{Lord Ernest Hives - Chair} R2/10.11.22. P. & R.{Sir Henry Royce} BATTERY. It is understood between us, including Mr. Day that we have no objection whatever to the P.&.R. battery, in fact we favour it, but we do not think it is wise to start with a battery of increased capa- city, but rather let us save some percentage of the weight and make it of the same capacity as we are at present using. I have pointed out from time to time that I am sure it is a question of increased reliability of the battery, combined with a dynamo which cuts in sufficiently low, and an easy means for charging at the garage.
