| RHC.{R. H. Coverley - Production Engineer} from EFC. X.8672 EFC/T9.2.29. We are handing to you herewith a 40/50 dynamo armature which has run over 12,000 miles, and the commutator of which has worn a little uneven. Would you kindly have the commutator skimmed up for us as we wish to fit the armature to a machine which is to be used for testing a special grade of brush. EFC. | ||
