| J 139 To BY.{R.W. Bailey - Chief Engineer} from E/JNR.{Charles L. Jenner} E/JNR.{Charles L. Jenner}1/HP.14.1.33. c. Hs.{Lord Ernest Hives - Chair} RHC.{R. H. Coverley - Production Engineer} re Peregrine Water Pump. The thrust screw and pump spindle and rotor of the 10,000 mile car are very badly worn, and the materials should be altered, making them similar to the Phantom - that is - we can use the thrust screw and pad E.79882/3 and make the pump spindle in nitralloy.
