I got this radio from an estate sale of a large radio collector. The man had restored many old TVs, radios and juke boxes. The key cylinder has serial no. 8c603 and should be obtainable if needed. The cradle for the pillow speaker serves as an on/off switch and no coins are required to operate it. Please see my photos. As always feel free to ask me any questions about any of my items for sale.
