Hello Richard:

Osterman's 3rd Edition has a little information. Apparently it was made
between 1945 and 1947 by the Allen d. Cardwell Manufacturing Corporation, a
family held corporation. It shows that it is 18 tubes with a rurret type
display.

A Google Search came up empty. Usually, you will find rare radios in
personal collections. The fact that I find none in personal websites is a
bad sign.

Never have seen one.

I think you need one for your collection.
