| 6000. To Rm.{William Robotham - Chief Engineer} from GWH.{George W. Hancock - Head Chateauroux} Cricklewood, Nov. 23rd, 1936. 25/30. Plug Troubles. As the saying goes you quickly hear of anything wrong, but seldom when alright. It is the case with our Champion plugs. We have fitted three sets and asked the drivers to let us know how they went on, so far we have not heard anything and one car has had them fitted for a month, the said same car, came in every week. We can assume there that th Champion plugs are overcoming the trouble experienced. We are doing our utmost to get hold of these drivers and will report as soon as we can collect the evidence.
