| X6004 RHC.{R. H. Coverley - Production Engineer} from EFC. EFC5/AD10.2.30. 6004 X.8665. 48-COIL ARMATURE DYNAMOS. For one of the three 48-coil armatures you have recently produced for us we shall require a new carcase and end bracket from production. The armature is being handed to Mr.Tooby. Will you please arrange for this machine to be made up and handed to us for test. In view of the dynamo position, this matter is rather urgent. It will be necessary for the end bracket to have its control brush holder securing holes plugged and re-drilled to convert the angle between the control brush and main positive brush from 122° to 131°.
