| X4021 Extract from RL/M6.11.26. ROLLS ROYCE F.10. X.3996. X.3832b. X.4021. Regarding the magnetos I quite think we must be able to fit either Thomson-Houston or Watford. I hope on Monday to be able to get into communication with Watfords, and ask them to send further and better samples of their machines to you. R.{Sir Henry Royce} | ||
