The early catalog advertisement insert states the following quote: - - - "The Midget Dynamo - Motor is a substantial little machine. It will run equally well as a motor or a dynamo (generator). It may be run as a motor by the current from a small dynamo, or from two or three cells of batteries. As a dynamo it has an output of about 10 watts, and will readily light one of our 6 c. p. miniature lamps. . . ."
