"PLYMOUTH RADIO & PHONOGRAPH CO.
One of the most important manufacturing industries in Plymouth is that of the Plymouth Radio & Phonograph company, which started in business in 1919, in the building originally occupied by the veneer company and later Mr. KADE.
The company specializes in manufacturing and selling the Plymouth Super-single radio set and the Pathephonic phonograph. The former is a seven-tube, single dial control radio set, which, by reason of its simple construction and superior workmanship, produces excellent results and has given general satisfaction to all purchasers. The Pathephonic is an unusual instrument, the company holding its own patent of special devices which make this equal to any high class phonograph on the market.
The officers of the company are as follows:
President and general manager - W. H. THOMMEN
Vice-president - H. W. BOLENS
Secretary-Treasurer - F. D. McINTYRE"
