You may be able to make the part out of wood. The particular vendor has a habit of disassembling radios and selling the cabinet, speaker and chassis separately at rather high "buy it now" prices. His stuff, his right, but I have never bought off him. I do not believe that the tubes on the vendors 'chassis are original. The originals should be Philco branded, manufactured by Sylvania and be the tall versions with Bakelite bases, not the shorter metal and wafer bases. (Sylvania released these tubes in 1938, spawning the portable radio.

Yu can run this radio on a 1.5V alkaline D cell for the filaments and ten 9V batteries in series. If you want to pay for long hours, build a 90 V battery eliminator. Personally, I would keep running the filaments off a dry cell, as it is rather difficult to build a stable 1.5V supply.
