Another point, and one which we feel deserves attention at the moment, is that the control brush of the dynamo is not spigotted, and every time an adjustment of this brush is made (which it has to be on the production testing of this machine) a disturbance in the bedding of the brush is almost certain to be produced, involving loss of time on test.
