| -2- Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}7/JH.7.4.38. between the plate which is a persistent 'judderer' and the one which is not, may it be due to the changing ratio of asbestos to bonding? If you are interested to persue this matter I would be glad to come to Chapel, with the two plates at any time to suit your convenience. I am pleased to tell you the new S7732 facing has now done just 1,000 miles in a Phantom III so far entirely satisfactory, and I would like to try a 10" facing of this material in a Bentley or an 11" in a 25/30 especially if your existing dies are suitable for moulding this material. Yours sincerely, | ||
