To Rm.{William Robotham - Chief Engineer} c. to Rm{William Robotham - Chief Engineer}/JE. 6001 Rm{William Robotham - Chief Engineer}/RC.{R. Childs}9/JH.24.8.37. M re K.L.G. F.50.X. Sparking Plugs. We have handed to Rm{William Robotham - Chief Engineer}/JE. one dozen K.L.G. sparking plugs for trial in the exhaust side of Phantom III unit No.6. This plug has a shorter reach and also a higher heat factor than the standard FF.30X. We understand that the existing standard plugs in the exhaust side were giving trouble due to pre-ignition.
