| To RHC.{R. H. Coverley - Production Engineer} X219 Hs{Lord Ernest Hives - Chair}/Mths.{Reg Matthews}11/KW.20.11.35. We should like a larger bore Bentley cylinder block and head in order to compare large and small bore units. Both cylinder block and head should have standard stud centres so that they can be placed on an existing standard bore unit. There should be a large bore cylinder head with 1.500 inlet valve off B-15 unit, since this unit has now been converted to a large bore 20/25. Hs{Lord Ernest Hives - Chair}/Mths.{Reg Matthews} | ||
