| R.{Sir Henry Royce} E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} COPY. BY11/J.17.8.31. X.7772. X.766. Re. Overheating of L.H. P.11. We attach hereto copy of a letter from R.R.A.I. relating to the above. It will be noted that they refer to the shutters in the bonnet being left open, but we cannot understand this as at the special request of R.R.A.I. all the L.H.P.11 are being supplied with plain bonnets.
