| c. BY/SS.{S. Smith} c. Hs.{Lord Ernest Hives - Chair} LODGE SPARKING PLUGS. The position in regard to the proposed improved "C" type detachable plug known as the C.150, is that it represents a slight improvement on the present standard "C" type detachable plug, but there is not such a vast difference between the improved type and the present to justify scrapping any plugs which may be in the course of construction to meet our requirements. The 4,000 plugs referred to may be accepted and utilised, but we trust at the end of that time the Lodge Company will be in a position to produce the new type. BY.{R.W. Bailey - Chief Engineer} | ||
