exciting find!!!!need help with research though

hubby found a radio/phono with a SEARS,ROEBUCK AND CO. logo as well as the name SILVERSTONE the patent is by RADIO CORPARATION OF AMERICA and HAZELTINE RESEARCH INC.
there is also an emblem that says RADIO MANUFACTURERS ASSOCIATION also in factory looking stenciling on the back it says NC 8/22/51 CATALOG AND MODEL #1066 CHASIS # 100.202
and the other marking on the back panel says SILVERSTONE 117VOLTS 85WATTS RADIO--60CYCLES 30WATTS PHONO

IF YOU KNOW ANYTHING ABOUT THIS BEAUTIFUL PEICE OR KNOW WHERE I COULD GET INFO PLEASE LET ME KNOW, I CANT FIND ANYTHING . THANK YOU

Please take a closer look at that brandname. UR initial post had an extra S in it. Sears sold thousands of radios, phonos & TVs etc. ( even some early 78-rpm records) under that name over many many years.

Try a Google search for "Silvertone Model 1066" and you'll likely find literature, service manuals, etc. JWH
