| Mr. Coverley. c. EFC. X7620 BY/RD29/W.9.10.24. X.8620. STARTER MOTOR ARMATURE. E.A.C.II. Following a request from EFC. to try an armature wound with smaller section wire, we send you herewith one blueprint of the following parts :- D.70830. Armature Assembly. D.70831. Wire for Armature Windings. As far as the material is concerned L.O.P. D.70812 can be worked to, the only difference being the depth of slot to take the armature winding milled in the armature core. We think the silk tubular sleeving used on the standard wire will also be suitable on this size for the experimental machine. Should you find that a smaller size would be better, if you will let us know we will endeavour to obtain same. Will you please put this in hand for one set as quickly as possible. BY/RD.
