| TO HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} R1/M8. 5. 24. Copy to CJ. " BY.{R.W. Bailey - Chief Engineer} " EP.{G. Eric Platford - Chief Quality Engineer} re. GREASE GUN LUBRICATION. +4400 For the purpose of lubricating road spring shackles, steering joints, etc. I believe that we ought to use grease in preference to heavy oil because its lubricating effect is more lasting, and better for keeping out mud. For this reason we shall have to adopt the two stage Enots Grease Gun which requires less muscular effort to use, and enables grease to be put into tight bearings (at present difficult to lubricate,) and also I understand provides a convenient means of gauging the amount of grease fed to the bearings.
