Description of the device written by Mr. Marco Contini, as well as in the brochure.

This very unusual disk gramophone was marketed by the United States Talking Machine Co. of Chicago, priced at a mere $3.50. It is housed in a small oak case, reminiscent of a cigar box, measuring only about 12 by 8 inches and only 3-1/2" tall. The mechanism consists of a 7" turntable which is hand-driven, with no motor. The tonearm is a simple piece of wood with a long needle pressed through the end, and a sliding weight to control the tracking pressure. The vibrations of the needle are transmitted through the solid wood to the other end of the tonearm, while a spring resonator connected to one or two sets of conventional listening tubes allows the sound to be heard.
