| To EFC. {E. Fowler Clarke - Electrical Engineer} X 4617E 31.1.30. X.4617E. 40/50 HP. Chassis Exide Batteries. Referring to Roy {Sir Henry Royce} /JTLO/HP.29.1.30, It will be very interesting to hear the result of the investigation by the manufacturers on this faulty case. It is incredible that any inherent defect should fail to be discovered on the electrical test, having seen the apparatus one can understand. GJ. | ||
