X8673 EFC3/T17.1.29. 28 SLOT ARMATURE DYNAMO WITH MORGANITE BRUSHES May we refer you to our EFC1/T13.12.28 asking for the removal of the dynamo from chassis 9-EX. This dynamo has run 10,000 miles with Morganite brushes which we are being urged to standardise, so as to have the brushes British. So that we may carefully examine the brushes and decide on their fitness, we should be pleased if you would arrange to carry out this item at your early convenience. EFC. | ||
