| To Sft.{Mr Swift} C. Wks. C. EFC. X 8672 BY/RD5/ML17.10.28. PHANTOM DYNAMO (28 SLOTS). COMMUTATOR END BRACKET D.71250.DC & D.71715.DC. We have instructed D.71715.DC to supersede D.71250.DC at the commencement of "H" Series, the only difference between them being the position of one pair of holes, i.e. for the control brush; this new position given to us by the Expl: Dept. is only preliminary and may require adjustment depending upon the average of the first 6 machines, we suggest therefore that the jig should not yet be altered and that the first few brackets be marked out. Will Sft.{Mr Swift} please arrange for EFC. to have the first 6 machines to check this position. BY/RD. | ||
