In answer to your By {R.W. Bailey - Chief Engineer} /Rd.6/W.15.3.33., we agree with the Works precision as it is important in any case they get the required output for the dynamo laid down in our specification. We have found it necessary in some instances to set the control brush to 120°C. on the Experimental machines tested, and we know from past experience that it is difficult to "lay down the law" with regard to control brush setting.
