| R.R. 235a (500 T) (S.D. 408. 26-4-17.) Bm. 2/158/13. X.2642. To R.{Sir Henry Royce} from EFC. cc to CJ. c. to EY. c. to Ep.{G. Eric Platford - Chief Quality Engineer} c. to EY/HEO. ORIGINAL EFC5/AT15.4.18. X.2642. R.R. SELF STARTER BRAKE EFFICIENCY TESTS. Referring to our note EFC3/T12.4.18. herewith please now receive blueprints of curves representing the Brake Efficiency Tests of the R.R. Self Starter Motor. 45 slot Slot Armature, and with the field coils in series and two in parallel, applied voltage being 12. The curves for the 24 and 17 slot armature will follow later, but we have rushed these through first beacuse we think they are of greater interest. EFC.
