| X. 4333. To RHC. {R. H. Coverley - Production Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 1/T30.5.24. X.4333 - 20 HP. CHASSIS DYNAMO R3. Herewith we return to you the above dynamo which you have just fitted with an annealed copper commutator with the standard No. of segments. For some unknown reason, the commutator seems to be somewhat distorted and unfit for running. Perhaps you would kindly give this your attention. EFC. {E. Fowler Clarke - Electrical Engineer} [Handwritten note:] Handed to you for test. RHC {R. H. Coverley - Production Engineer} | ||
