| To RHC.{R. H. Coverley - Production Engineer} X756 Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}1/EW.10.1.36. Brake Drums for Bentley in 0.9% Carbon Steel. We have recently had a visit from the Chief Chemist of Ferodo Ltd. He has pointed out to us that the Millenite now supplied to us by Lake & Elliot and for which we pay a very high price has deteriorated from the quality of the samples originally supplied, and is no longer especially suitable for a brake drum material. We are wanting to try a pair of drums in 0.9% carbon steel, and we want to produce them as economically as possible, so have decided on Bentley size; made from a forging. Will you please make a pair to G.100981, and fit them to B-23-AE. Hs{Lord Ernest Hives - Chair}/A.F. Martindale. | ||
