There are also some various spots of staining on the cabinet. There are many spots on the lid and a few sides of radio that appear to have also been touched up. This appears to be a scarcer version of the SW-5. All of the individual wires inside appear to be in good condition with no fraying.
The flange around the base has been repainted with a similar color. Needless to say, this radio is untested due the missing pieces.
