| PERI! CRANK. E2/M8.4.22. ORIGINAL To Hy.{Tom Haldenby - Plant Engineer} from E.{Mr Elliott - Chief Engineer} c. to CJ. c. to WOr.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} (Le CanadelHenry Royce's French residence.) ✓ PEREGRINE CRANKSHAFT. X4434 We have duly received the returned print of LeC 1540 shewing the lubrication holes in the journals and crank pins. We feel a bit afraid of using such a large oil hole, and we should like to suggest that this should be reduced to at least 3/16 instead of 7/32 diameter. E.{Mr Elliott - Chief Engineer} | ||
