Wraith II Gearbox. We shall shortly be sending a design for a 2nd speed coupling on the lines of N.Sch.4824 for the Phantom III. We expect that it will be necessary to modify the splines on the rear end of the 2nd motion shaft from those already instructed. Therefore, the broach for these splines should not be ordered until our revised scheme is received, E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} | ||
