I believe the radio is all original. It is in good physical condition. Two of the knobs has small chips on their rims.
Nice radio that will need a little restoration or would make a nice display piece. The item "ANTIQUE ZENITH TABLE AM/SHORTWAVE RADIO MODEL 5S 327" is in sale since Wednesday, May 8, 2019.
