All letters must be addressed to the Company, not to individuals DIRECTORS: J.{Mr Johnson W.M.} ALFRED HOPPS. BERNARD HOPPS. ALEC M.{Mr Moon / Mr Moore} LODGE. F.{Mr Friese} BRODIE LODGE. For the attention of Mr. West. WST Dear Sirs, We are sending you under separate cover to-day, twenty-four X460B sparking plugs, to replace the twenty-four X420B plugs handed to Mr. Pacy when he called at your works on January 7th. The X460B supersedes the X420B, and incorporates a new design of earth electrode, which should give the best possible thermal conductivity with the body, and also prevent any possibility of a failure similar to that experienced with the X420B. We shall be interested to have your report upon these plugs when you have had an opportunity of giving them a test. We should also be very interested to hear whether you are yet in a position to give us any information regarding the tests on X435B, X402B/1, X453B, and X400B (stellited). Yours faithfully, LODGE PLUGS LIMITED. | ||
