| Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} from Rm.{William Robotham - Chief Engineer} 300a Rm{William Robotham - Chief Engineer}4/R.30.7.37. The point burning you are experiencing appears to be extraordinary. We recommend that you try a set of Champion plugs, which you could obtain from Paris. I am told that the wireless suppressors make point burning worse. If you have any fitted you might remove them. I expect to come out to France about Wednes- day of next week, but am not certain yet.
