Bailey - Chief Engineer} [crossed out] c. to E.{Mr Elliott - Chief Engineer} [crossed out] EP{G. Eric Platford - Chief Quality Engineer}6/F15518. 15th.May, 1918. RE. SPARKING PLUGS. With reference to your excellent report on the above, ref. EH3/G8518, as per our consultation yesterday, I think it very important that the Lodge plug you refer to as the best plug we have for general service, should be the Lodge K.R.3. type, and not Lodge K.R. The Lodge K.R. plug, as you are aware, is the type which was proved to be very bad for pre-ignition, and if the information is circulated as per your memo., there is likely to be confusion. EP.{G.
