Hancock - Head Chateauroux} 9/JR. {Mr James Royce} 22.5.37. Wraith Starter Motor. The design of the starter motor calls for a small pinion and smaller screwed shaft. We are not in the position to know whether this design will be satisfactory for engaging or damaging the flywheel teeth. I propose that this part of the unit could be quickly made and tested without waiting for a complete engine or starter motor. A flywheel ring and a drive would be the other units needed.
