| Hs.{Lord Ernest Hives - Chair} from ROY.{Sir Henry Royce} x967 ROY{Sir Henry Royce} 7/MG5.3.26 Price's Oils The Price's Company have replied as copy attached regarding your recent request for information as to the constituents of their "Motorine" Oils - which I rather think is what we both expected. I believe the success of Price's Compound Oils depends in a large measure on the nature of the fatty oils used, and naturally they look on this as rather a Trade secret.
