| COPY. To Hy.{Tom Haldenby - Plant Engineer} from R.. Copy to J.{Mr Johnson W.M.} Copy to E.{Mr Elliott - Chief Engineer} Copy to Wor.{Arthur Wormald - General Works Manager} for EH. It is no use including the 2" bumps in any reports of fatigue tests. We do not know their relative value, but should think it is very little compared with 3" bumps. We hope the radiators will soon be good enough to also stand 3" bumps. R.{Sir Henry Royce} X/331 | ||
