Martindale} 1113 Rm{William Robotham - Chief Engineer}/AFM{Anthony F. Martindale}1/R.1.7.37. INTERNAL BRAKE NOISE - P.III. With reference to your memo of 26th June, will you please let us know the name of the maker of the H.P.G. (high pressure grease) you use at Cricklewood for smearing on the toggles, and his name for this grease, if different from the above. We have no objection to instructing all chassis to be built up as you suggest, but we ourselves will try using Keenol grease which may prove better.
