| X4425 Hs{Lord Ernest Hives - Chair}2/LG. 14th. Feb. 1922. Messrs. The Lodge Sparking Plug Co., RUGBY. Dear Sirs, We have received 6 Steatite Sparking Plugs model CD. for which, many thanks. So far on our tests they promise to be an improvement over the previous types. We should be greatly obliged if you could let us have another half-dozen of these plugs because for our tests we need 6 for running in the Car and 6 for running on the Bench Test. Yours faithfully, | ||
