| X5663 To R.{Sir Henry Royce} from EFC. c. BJ. E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer} EFC1/T16.7.28. 20 H.P. DYNAMO WITH COARSER GAUGE ARMATURE FOR HIGHER OUTPUT. Further to our EFC5/T11.7.28, we now attach blue print shewing curve of output of the above in comparison with the representative standard output, as referred to therein. EFC. | ||
