| C sent to RHC.{R. H. Coverley - Production Engineer} COPY. To Rm.{William Robotham - Chief Engineer} Kingsbury. Dec. 3rd. 1936. I am sending you a cylinder block taken off A.F. Ferguson's Bentley, mileage 8,229. The cylinder bores are badly worn, are not true with the base, are oval, and was over-oiling 700 M.P.G. It will be in case No.65. We have had the bores just touvhed on the grinding machine to show ovality, out of truth with base, etc. It shows clearly the trouble with our present method of boring and honing.
