| 5006 Expl. Dept. Hs{Lord Ernest Hives - Chair}/Les.24/MJ. 10th. August, 1934. The British Tyre & Rubber Co. Ltd., Leyland, Lancs. For the attention of Mr. Evans.. Dear Sir, We are sending you herewith replacement prints of F.60398, F.60400 and F.60411. These have had the radii modified as suggested. We are sending you a four capacity mould for F.60399, also enough steel inserts for completing the present order. Unfortunately these inserts have not the latest radii. If you can get the inserts made correctly please do. In view of the fact that the rubbers you have so far supplied have been softer than we are accustomed to, will you please produce half the order to your next grade harder rubber, that is, Durometer 65 to 70. Yours faithfully, For Rolls-Royce Ltd. | ||
