| x4876 To Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} E.1/HP.29.11.33. c. ROY.{Sir Henry Royce} re Searle Radiator Block. I am passing on to you specimens of the above, as referred to in ROY{Sir Henry Royce}13/MG.13.11.33. Personally I think this block would not be as efficient as the Harrison type, and at the moment do not see that we would gain much by making a test of this type. E.{Mr Elliott - Chief Engineer} | ||
