ALEX M.{Mr Moon / Mr Moore} LODGE. F.{Mr Friese} BRODIE LODGE. All letters must be addressed to the Company, not to individuals Dear Mr. Robotham, In reference to your letter of the 24th. March last and your telephone request to-day, we are sending you herewith one dozen of our new type H14. sparking plug with 14 m/m thread. As explained to you on the telephone, this is not quite in its final form as regards the external dimensions of the mica insulation and the radiator. If you find the performance of this plug satisfactory we should like to know if you would like it supplied with or without the radiator. The radiator undoubtedly assists to some extent in cooling the plug, but we think it will not run unduly hot in your engines without the radiator, if you object to the appearance of the latter. Yours sincerely, Bernard Hopps. Enclo: (Plugs) ENCLOSURE Nº 926 "JUSTSO" | ||
