All letters must be addressed to the Company, not to individuals Dear Mr. West, I am sending you herewith one of our 14 mm. BR.{T. E. Bellringer - Repair Manager} plugs, which we have been supplying for a number of years for racing cars and motor cycles. The Champion plug which you showed me is evidently a copy of our BR.{T. E. Bellringer - Repair Manager} plug, excepting that they are using a ceramic insulator externally, whereas we prefer to use mica all through. This type of BR.{T. E. Bellringer - Repair Manager} plug is made in various heat factors for different types of engines, and will withstand the greatest heat of any plug we make. Sincerely yours, Bernard Hopps 1 Enclo: (BR50. plug) ENCLOSURE Nº 413 "JUSTSO" | ||
