Offered here is a hard plastic round dial with hard plastic escutcheon and glass cover for a Silvertone model 4470 antique table-top radio.  Please note the light damage to the escutcheon on the one edge.  The escutcheon is 3-7/8" ID and just slightly over 4-7/8" OD.  The flat dial itself is also right at 3-7/8" OD
