All letters must be addressed to the Company, not to individuals For the attention of Mr. West. Dear Sirs, In accordance with your request we have developed a new plug for your 3½ litre Bentley. This plug is fitted with our latest method of brazed stamping and the area of the electrode exposed to the spark has been materially increased in order to overcome rapid erosion. The new plug has been designated X512, and one dozen are being sent to you to-day for test, and we shall be very glad to have your report at your earliest convenience. Yours faithfully, LODGE PLUGS LIMITED. DIRECTOR. | ||
