| HR Hs.{Lord Ernest Hives - Chair} from ROY.{Sir Henry Royce} X967 ROY{Sir Henry Royce}16/MG24.3.24. Price's people write asking if we can report any data yet as to our tests with Zero Huile de Luxe, and are sending forward, free of charge, a 5 gallon drum of Winter Huile de Luxe, which they claim has 50% greater body than the zero grade and is therefore preferable for use during the summer months and under other severe conditions of load and temperature. I have asked Stores to pass it to you on receipt. ROY.{Sir Henry Royce} | ||
