Recaping a 1937 Zenith 6S299

[GinoRoth]

Last month I got an old Zenith Black Dial Radio (Model 6S299) from 1937. I had to rebuild a new cabinet for it because the old one was beyond repair. I had been looking at pictures of the old Westinghouse Columnaires and thought they were graceful looking and well designed. Zenith made consoles but nothing like the Columnaire so I decided to make one and I am attaching a picture of how the cabinet turned out. Over the last week I have been cleaning up the chassis and replacing all the capacitors and resistors. With each new one added, the sound returned and became stronger as I went along - until I came to the last item. I don't know what this is - it has the color bars of Red, Orange and Silver - only the 3 bars. the body is brown like a plastic or baklite. At first I thought it was an old molded capacitor of .023 ohms but when I replaced it with an orange drop the radio stopped working. Can anyone identify this thing and tell me what I can replace it with?
