X.3804 X.4003 X.1807 In our memo. E2/M26.11.26., we gave Mr. Royce's criticisms of the scheme submitted for the above.

We send this to you only as a suggestion, not yet approved by R.{Sir Henry Royce} Diagram annotations: 5 HEX HEADED SCREWS LOCKED BY TAB WASHERS PINION DRIVING SPUR OR ANNULUS 12 STAR TEETH TO LOCK NUT Faint background text (mirrored and upside down): CERTIFICATE OF INSPECTION OF ROLLS ROYCE ENGINES AND... | ||
