| FROM E.{Mr Elliott - Chief Engineer} Copy to HS.{Lord Ernest Hives - Chair} re. LIGHTER PHANTOM ENGINE. X8090 X8820 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. [STAMP] ORIGINAL [STAMP] RECEIVED OCT 14 E.{Mr Elliott - Chief Engineer} | ||
