| X.2814. To Wor. {Arthur Wormald - General Works Manager} for Mr. Ellis. From EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 3/AT7.11.17. X.2814. X.3173. RE BATTERY IGNITION FOR AERO ENGINES. Will you kindly have the cores which you have taken from the Remy 6 and Remy 12 cylinder coils temporarily rewound with the same number of primary turns of the same gauge of wire as was taken off so as to be as nearly as possible the same as the original primary winding, and hand this over to us so that we may make a simple comparison of the inductances of these two primary windings.
