| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to BJ. Hs.{Lord Ernest Hives - Chair} X8090 E1/M13.10.26. RE. LIGHTER PHANTOM ENGINE. X.8090 X.8840 Referring to the valve rocker cover of the lighter Phantom engine, we should prefer to retain this as a casting rather than use the sheet metal construction, and our idea is to make this part from one of the light magnesium alloys. Perhaps you would kindly see what could be done. . E.{Mr Elliott - Chief Engineer} | ||
