| To By.{R.W. Bailey - Chief Engineer} c. to RHC.{R. H. Coverley - Production Engineer} X1020 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}13/KW.18.2.36. Main Bearings for 25/30 HP. Production Engines. Will you please instruct for production, intermediate and main bearings having grooves exactly similar to the Hall's metal bearings standard in the large bore Bentley. We have found these necessary when using Hall's metal big end bearings, in spite of the fact that the main bearings for the 25/30 are in white metal.
