| To CJ. from E.O. X 4284a EFC3/T4.5.21. X.4284 - DELCO IGNITION. In answer to your CJ18/E28.4.21, apparently we have very little which has been written by Mr. Royce directly concerning Delco Ignition, but we are sending you along some matter written by Mr. Olley with reference to the Delco Liberty sets as used on the Liberty aero engine, together with three notes from Mr. Royce. This is all that can be found which appears suitable to your request. EFC. | ||
