| X 8445 EFC. BY8/H.{Arthur M. Hanbury - Head Complaints} 27.10.24. 40/50 HP. CHASSIS 42-EM. I am sending you herewith coil taken from the above car as defective. The coil in question has been replaced by a new one, but I am interested in knowing just why this particular coil failed. The object I have in checking out all of these failures is of course to find whether they failed for a common reason which may demand attention even on new design. BY.{R.W. Bailey - Chief Engineer} By | ||
