DIRECTORS: J.{Mr Johnson W.M.} ALFRED HOPPS BERNARD HOPPS ALEC M.{Mr Moon / Mr Moore} LODGE F.{Mr Friese} BRODIE LODGE All letters must be addressed to the Company, not to individuals For the attention of Mr. Robotham. Dear Sirs, In accordance with the arrangement made with Mr. Robotham at our recent interview, we are sending you under separate cover 3 dozen of our Model MC3. plugs for test in your 40/50 or your 20/25 car engines. We have supplied 1 1/2 dozen with smooth finished mica insulation, marked MC3. on hexagon; and 1 1/2 dozen with stepped mica finish, marked MC3S. on hexagon; and shall be glad to know which of these two you prefer. We have fitted our weatherproof terminal to all these plugs, but it is of course understood that if this fitting is not approved we can supply similar plugs with the ordinary milled nut terminal. You will find these MC3. plugs will withstand considerably more heat than the Model C. which you are at present using. We await your report on these plugs with interest. Yours faithfully, LODGE PLUGS LIMITED. Bernard Hopps. DIRECTOR. | ||
