| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} X. 985 R6/M9.11.26. RE. ANGLO-PERSIAN BP. PETROL. We are interested in this because it is a British Co., but I understand their standard spirit is more prone to detonate than say Shell. Is this so? Can it be cured by adding some other kind (blending), or by dope - salts of lead, etc. My friend is interested as a shareholder, and well known to the directors. Can you let me have a report of your experience, and the usual cure. R.{Sir Henry Royce} | ||
