| X 6004. To RHC.{R. H. Coverley - Production Engineer} from EFC. EFC6/AD4.2.30. 6004 X.8665. INTERMEDIATE OUTPUT DYNAMOS. We now hand you dynamo SS{S. Smith}2, together with the second of the three new armatures you recently had made for us. Will you kindly fit this new armature and also a new commutator end bracket, modified as for the previous machine, i.e. a standard end bracket on which the existing control brush securing holes have been plugged and new holes drilled so as to make the angle between the positive holder and the control holder 131° instead of 122°.
