This is a cabinet from a 1930 Hollis Baird TV adaptor after restoration. It uses the C-3-5 shortwave chassis that is in the Hollis Baird console in our collection. This set received 2-3 mHz TV transmissions and connected to the neon of a scanning disk. Eventually we hope to find a chassis for this set. The knobs are probably not right. We will attempt to get pictures of an original and find the proper knobs.
