| X.4237 8.10.21. Extract from E2/G8.10.21. X.4219 X.4237 We shall very shortly send you an alteration to the fan pulley required by the change in the slipper drive, and at the same time we are putting up the size of the fan somewhat, as Mr. Royce thought the one he saw on Goshawk 11 chassis was too small.
