| O.O. From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to By.{R.W. Bailey - Chief Engineer} N=250. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}2/MJ.10.11.30. PHANTOM II SQUARE RADIATOR TUBES. We note that E.81389 tube has not been produced. We understand that the tools for producing this tube are available and we think that we should certainly order sufficient to build up a radiator, as it was a type on which R.{Sir Henry Royce} was particularly keen.
