| X515 BY. {R.W. Bailey - Chief Engineer} from ROY. {Mr H. Royce - Buyer} c. to Hs. {Lord Ernest Hives - Chair} ROY {Mr H. Royce - Buyer} 3/MG21.8.28 Under existing arrangements we use Duckham's H.B.B.Grease for packing Hoffmann Ball Bearings, in accordance with recommendations from the Hoffmann Company. The latter now write as copy attached (signed by Mr. Cooper, their Research Engineer), and, as we have special arrangements with Messrs. Price covering such supplies, which show a marked economy over the Duckham arrangements, I suggest we consider the substitution of Belmoline C in place of Duckham's H.B.B.Grease. Supplies of Belmoline C can be obtained at at once if you consider it necessary to make tests in addition to the recommendation given by the Hoffmann Company. ROY. {Mr H. Royce - Buyer} ENCLOSURE.
