You can assume that all further engines will be fitted with camshafts Ex.15042 and Fescolised chromium plated tappets until the decision is reversed. We have so far only received two of the Textolite gears with the holes deleted because only two wheel centres have been sent away. Will you please despatch further hubs so that we can ensure a supply of these parts. We are sending copies of all these notes on the specification of SpectreCodename for Phantom III 2 to E.{Mr Elliott - Chief Engineer}, and By.{R.W. Bailey - Chief Engineer}, so that they can keep track of what we are doing and avoid instructing quantities of parts which are not up to date.
