| X601 Hs{Lord Ernest Hives - Chair}4/LG. 8th. Aug. 1921. The Lodge Sparking Plug Co.,Ltd., Rugby. Dear Sirs, We have been testing the plugs with the pot insulation which you sent to us sometime ago. So far they appear to behave satisfactorily. We should like to know whether you are yet in a position to produce these plugs commercially and if so, on what terms. We are obtaining very excellent results with some American porcelain plugs which are considerably less in price to what you charge. Yours faithfully, | ||
