| 86107 E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. c. to Roy.{Sir Henry Royce} Hs{Lord Ernest Hives - Chair}/Wst.6/MA.28.9.33. BATTERIES. Referring to Roy.{Sir Henry Royce}5/MG.27.9.33 we could not entertain the idea of using the Bentley type of battery on the 20/25 until such times as we have a vibrator controlled dynamo system as the thinner plates in the Bentley battery with the use of the third brush dynamo would have much less life.
