X6131 c/o Rolls-Royce, 32-34, East 57th. Street, N.Y. Aero Engine Ignition. We have obtained a 12 cyl screened battery ignition distributor and coil from the Delco Aviation Corp and we should like to know if you can find out whether they are actually in production with aero sets. The R.A.E.'s objection here to battery ignition is purely on the score of increased radio disturbance on aircraft. Have the Americans found this radio disturbance serious? We are now interested in fully radio screened sparking plugs and any samples available we should be pleased to have for comparison with our English ones. Hs{Lord Ernest Hives - Chair}/Wst. | ||
