Dear Sirs, We are at present testing different makes of Plugs, before ordering them for our series. We have allready tested most of the best French and Swiss marks, but should like to make a trial with the "LODGE PLUGS" On approaching Mr. Brook on this subject, he informed us that you use this plug exclusively and he kindly offered us to have some of them sent us on his return to England. We should be very much obliged to you if you would kindly send us 6 Lodge Plugs, or 6 of each types, in case you use two types, indicating the types, and sending us debit note for their value. Mr. Brook spoke about a Plug with a metal core, that you use for your aviation motor and that would be interesting for us, as in our sleeve valve cars, the porcelaine plugs crack if they are not of the best quality, seeing that they are located deeply set in the combustion head and that they are called upon to work at a high combustion temperature. We very much thank you in advance for your kindness in this matter and beg to remain, dear Sirs, Yours very sincerely, Soc.
