There are a number of antique radio groups out there, often due to how it was stored the radio is salvageable but the case not so... Maybe you should try them.
Unless they are like in brand new condition, there seems to be not much of a big demand for these furniture type 1920s radios unless they exhibit an art deco design. I see complete radios selling for only a couple of hundred dollars at most and a cabinet alone is probably $50. or less.
