Dear Mr. Grylls, Many thanks for your letter of the 30th December enclosing arrangement drawing of the 6.50-16 tyre and wheel. I am afraid that we cannot recommend for road use the Aero valve no. 7066 in its normal form, but the whole question is being investigated and i will let you know, as soon as possible, what can be done to provide the six tubes you require. in the meantime it was agreed that we should not yet approach Mr. Worth. Yours faithfully, for DUNLOP RUBBER CO., [Signature] Manager - Car Manfrs. Divn. [Logo: 1938 DUNLOP SYMBOL OF GROWTH] | ||
