| X6004 RHC.{R. H. Coverley - Production Engineer} EFC. BY/RD9/N.2.10.29. Re: 40/50 HP. Chassis Dynamo - Intermediate Output. Will you please put in hand three armatures to our Part List D.72238, blueprints of which are already in your possession. We have already had three armatures made and tested, and the correct position for the windings now determined, and you will notice that we have added to the above Part List a new Winding Diagram to which these three new armatures should be wound.
