P.C. Please receive herewith D.CD.540 showing the bronze brush gear recently instructed experimentally on D.CD.214, arranged in conjunction with the 34 slot armature. It has been necessary to lengthen the armature shaft .200 to accommodate the new brush gear, and this requires the water pump shaft to be correspondingly shortened.
