| X6079 Sft{Mr Swift}/Mr. Brock. c. EFC. re. PHANTOM II. STARTER MOTORS. The starter motor R.85.E. which has given so much trouble, is now functioning very satisfactorily after "C" modification has been carried out. False starts are very few. I have just done 100 consecutive starts with only two failures. Mx.{John H Maddocks - Chief Proving Officer} [STAMPED] RECEIVED 1 APR 1931 | ||
