| To RHC.{R. H. Coverley - Production Engineer} c. to H1. X1070 Hs{Lord Ernest Hives - Chair}/Smth.20/EW.4.1.36. Solid Hall's Metal Bearings. We think that solid bearings made of 7% tin composition and then annealed in the part machined condition will be more satisfactory than the 10% tin ones previously instructed. Since these latter are in abeyance, will you please make us up some of the lower tin content, but annealed. Hs{Lord Ernest Hives - Chair}/Smth. | ||
