| ROLLS-ROYCE LTD. INSTRUCTIONS. To EFC {E. Fowler Clarke - Electrical Engineer} Order No. AC.75. Customer's No. X 4105 Cut-out Contact-Point Experiments. "The cut-out fitted to 10GIII which has completed practically 14000 miles running, is in very good condition. Wear is very slight, and the sliding action is still good. The "A" type cut-out removed from 8GIII ran 8902 miles and kept in good condition, but not sliding very much, owing to the greater stiffness of spring compared with the 150 track type. Signed H.A. This Sheet must be filed on completion of the work. | ||
