| Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} c. Hs.{Lord Ernest Hives - Chair} c. By.{R.W. Bailey - Chief Engineer} c. Mx.{John H Maddocks - Chief Proving Officer} c. LA.{L. A. Archer} 664. Rm{William Robotham - Chief Engineer}1/R.26.4.38. re: Your Chassis WXA-1 - Spark Plugs. Neither Mx.{John H Maddocks - Chief Proving Officer} nor LA.{L. A. Archer} who have tested these plugs independently have been able to get misfires on the road. We should like to have the opportunity of sending our Plug Specialist down to London to run them in your own car, as possibly it is some other defect in the electrical system which, in conjunction with plugs that are not quite 100%, will produce misfiring.
