| COPY. [Handwritten]: SCAV/O Notg filed in SCAVOS To J.{Mr Johnson W.M.} from R.{Sir Henry Royce} R10/1B4515. My dear J: Re Leaky Radiators. We are awaiting experiments to find the best way of treating the crinkled type of radiator. In the meantime I am in favour of the round tube Marston radiator for current work, this being lightest and most efficient. F.H.R. [Watermark]: HYDE & JOHNSON | ||
