| X4425 BY4/H.{Arthur M. Hanbury - Head Complaints} 30.3.25. LODGE SPARKING PLUGS. PHANTOM CHASSIS. -------------------------------------- The Lodge Company have improved their detachable porcelain insulated sparking plug by some improvement in insulating. HS.{Lord Ernest Hives - Chair} has tried this out, and found they are an advantage. In future when we are buying plugs, he wishes us to buy this particular type. The number that Hs.{Lord Ernest Hives - Chair} has given to me is "C.150." As judged by our previous experience, the "150" is not a type. It will therefore be necessary for us to write to Lodge, explain precisely the type of plug we are discussing, ask for a type lettering for same, and let the D.O. know, and arrange in future to order such plugs, in place of the type at present being used.
