In one Machine we have found pronounced Electrical Noise, the cause of which we are carefully investigating, but we have also found that when the Whittle Belt is tight a noise is produced similar in pitch and quality to the electrical hum, and we ask you to investigate this actually under the conditions which exist on the Car. We suggest this matter is of very great importance and should be followed up immediately. Accordingly, we shall be glad to know by return a day next week which is convenient for our representative to visit you. We would suggest Tuesday.
