| From Lodge Plugs Ltd. To W. A.{Mr Adams} Robotham Esq. Sheet No. 2. Date 27.10.34. with the car, even with my moderate driving, in 2,000 miles. I have sent them to Mr. West at his request. I certainly think you should drop wrapped plugs and get on to the washer type, the extra cost is negligible compared with the extra life and reliability. Yours sincerely, Bernard Hopps.
