| 500 Wsl- What is the position with regard to these Coils? S/W. Rm.{William Robotham - Chief Engineer} Slow Running of 25/30. Rm{William Robotham - Chief Engineer} Can you say when we can get some coils for this job? We have had one of our Trials Cars converted so far as the distributor is concerned, but it is difficult to detect any difference in the slow running. We understand that much of the improvement is due to the coil it is intended to use, but so far we have been unable to get any for use in connection with this modification. Cx.{Major Len W. Cox - Advertising Manager} 2 Coils immediately More on request | ||
