This is one of only three radios built to display the advantages of the "Tinkertoy" technology developed in a secret project by the National Bureau of Standards (NBS) for the Navy Bureau of Aeronautics. These models were created to show commercial radio manufacturers the pre-transistor technology. Motorola for one used the technology in some of their portable models. For instance the Motorola 66L1 charcoal and 66L2 suntan (Chassis HS-515). See also this Tinkertoy-article plus an article in German.
One of the photos at the model page for 5P31A - HS559 shows one version of the Tinkertoy stack with a tube socket at the top holding the 1DN5 detector/audio-preamp tube.
The schematic page with the top view of the parts layout for model 5P21B - HS633 shows a different Tinkertoy single stack module without a tube socket.
