| X5663 To R. {Sir Henry Royce} from EFC. {E. Fowler Clarke - Electrical Engineer} c. BJ. E. {Mr Elliott - Chief Engineer} BY. {R.W. Bailey - Chief Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 1/T16.7.28. 20 H.P. DYNAMO WITH COARSER GAUGE ARMATURE FOR HIGHER OUTPUT. Further to our EFC {E. Fowler Clarke - Electrical Engineer} 5/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. {E.
