I picked up the Stromberg this evening. It included the back.
I also bought a 1920(s) radio transmitter in a wooden box from him. I already have the Crosley set in my collection. His Crosley tv is missing the lid. He also had some early 1950 RCA B/W consoles which I don't have room for. He said he is looking for a postwar mirror-in-lid like the 1949 Spartan but I told him mine is not for sale.
