| ~162 By.{R.W. Bailey - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. c. to E.{Mr Elliott - Chief Engineer} c. to Mx.{John H Maddocks - Chief Proving Officer} Hs{Lord Ernest Hives - Chair}/Wst.1/MA.11.1.34. WESTON AMMETER. We are much concerned with the failure of Weston ammeters in the Test Dept. Although we have had ammeters operating on experimental cars and on the last two 10,000 mile tests we have not experienced any trouble at all. We understand Messrs. Weston's representative is coming over to-day to see you regarding these failures and we should be interested to join you when he arrives. A specially damped Lucas ammeter is being tested in the Experimental Dept., and you might be interested to examine a sample sometime, as the existing Lucas on the 20/25 chassis we understand has given no trouble.
