| To Rm.{William Robotham - Chief Engineer} from Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} By.{R.W. Bailey - Chief Engineer} Mx.{John H Maddocks - Chief Proving Officer} 11/3 Cricklewood August 16th 1937. PHANTOM III. K.L.G. FE.30 PLUGS I have examined the plugs of chassis 3.BU.116 after 3651 miles and 3.AX.53 after 3,177 miles. There is no sign of the centre electrode burning on any of these plugs. The gaps have not altered. There does not appear to be any cause for alarm with the use of these plugs in England. No car has come in with plug trouble, that is the reason I cannot get evidence. They are not in the Depot to examine. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} | ||
