| To Rm.{William Robotham - Chief Engineer} C. to Rm{William Robotham - Chief Engineer}/Wst. [Handwritten] West What about this Attached is a report on sparking plugs K.L.G.E.26. removed from 36-EX, these plugs are the same type as present standard, but were an early supply. We again stress the fact that these plugs are burning away too quickly at the points and the matter requires urgent attention from Wst. Rm{William Robotham - Chief Engineer}/F.Dodd. [Handwritten] RM{William Robotham - Chief Engineer} The special plugs which have been fitted to 36EX have copper central electrodes with pure nickel tips in an endeavour to keep the electrode cooler and reduce erosion. We are watching these plugs and have ordered a further quantity. Wst. | ||
