Your Ref. Our Ref. BH/EW. Date: 4 May 1933. 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 reference to your letter of April 29th. requesting plugs with thicker electrodes for test on your 25 h.p. car, as promised we are sending you under separate cover one dozen Model HD{Mr Hayward/Mr Huddy}3. plugs fitted with this thicker electrode and with heavier earth points to resist burning. May we suggest that these HD{Mr Hayward/Mr Huddy}3. plugs be tested in comparison with the HC3. plugs which we have already sent you, as apart from the question of burning of the electrodes we still feel that the HC3. plugs will probably be found to be more suitable. We await your report on the performance of these two types of plugs with great interest. Yours faithfully, LODGE PLUGS LIMITED. [Signature of Bernard Hopps] DIRECTOR | ||
