| -2- Hs{Lord Ernest Hives - Chair}/Smth.3/KW.6.7.36. Comparing these with the figures for American "Hycoe" given in our letter of May 1st, it would seem that the English material is stronger in some directions, but weaker in others. In view of this we do not think it worth while to proceed further with the English facings for the moment. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
