The early version Arvin model 517 Rhythm Junior is without the three vertical bars on front of the loudspeaker. The Arvin model 517 Rhythm Junior with 6 3/16 inch dial covers 545 - 171 meters (550 - 1750 kc = incl 1600 to 1700 police bands) and 16.65 - 52.6 meters (5.7 - 18 mc).

    Rider's shows that the chassis has been published 1936 (or before) but this form is not on the catalog 1937 of The Belknap Hardware & Manufacturing Co. but the new version.
