| Rm{William Robotham - Chief Engineer}5/R.{Sir Henry Royce} October, 9th, 1937. L.G. Callingham, Esq., Shell-Mex & B.P. Ltd., Victoria Embankment, W.C.2. Dear Mr. Callingham, Thank you for your letter of October 7th. We will query the recommendation of National Benzole Mixture with the people who wrote the letter from which you quote. We would point out, however, that in practice we have found that Benzole mixture is considerably better than the octane value would lead one to suppose. Yours sincerely, | ||
