Messrs. Rolls-Royce Ltd.,
Derby.

For the Attention of Mr. H.E. West.

Dear Mr. West,

Further to my telephone conversation with you, this is just a note to confirm that I think it would be mutually helpful if you could arrange to call here the next time you come this way, as I want to show you our latest development on our aircraft plug job (which seems very healthy); while, following Mr. Browne's visit to Derby this week, there are also some car items which I think we could usefully review.

With regard to the further samples of aircraft plugs for you, we have just received the long-awaited bar of Invar steel. We have the insulators ready and are therefore proceeding to make up the samples. I am anxious to push on with these as I am now inclined to feel that we are reaching finality in meeting endurance requirements.

Yours truly,

N. F.{Mr Friese} STOCKBRIDGE,
Managing Director.
