| Roy.{Sir Henry Royce} from EFC. X3498 EFCl/AD11.7.29. FERRANTI AMMETER. Herewith we hand to you Ferranti ammeter which we regret has become damaged. Will you please have this returned to the makers for repair. If they consider the reason for damage occurring to be due to a weakness in the instrument, we should like an improvement made. We want the ammeter back to continue the 10,000 mile test. EFC. | ||
