| S.S. 1950 (BD{Mr Berend}/6 10-2-17) M.P. 180805 X4196. Extract from Hs{Lord Ernest Hives - Chair}7/LG4.10.20. X.1812. X.3413. IGNITION PLUGS. X.3905. X.4196. The American Champion Sparking Plugs we find are quite good. They have solely procelain insulators. The porcelain used on the Champion plug is more reliable than the average. The appearance of the plug does not imprress one but actually in practice we have found no faults. Mr. Olley in his Oy6/G23.8.20, asks they they might have permission to use these plugs for repair work and for R.R. cars produced in America. The Champion plugs have been used successfully at the New York Service Station for several years. We recommend that the Champion plugs are used in America and we should like to hear from them how they consider the present Lodge plug compares with the Champion plug under their conditiosn.
