Zworykin wrote an article for the December 1929 Radio Engineering magazine describing this set. His byline listed him at Westinghouse in Pittsburgh. In this picture you can see the lab prototype in a plain wood box and the display version in the Radiola 47 cabinet. Note that you can just make out the Westinghouse logo on the crt in the Radiola picture.
