bigbad - You can see some examples of the Jim Carter Hammertone paint at My '41 Link below.
The radio that I purchased had the original paint on it and although it was a bit darker than the Carter paint it was hammertone with the fisheye effect. I don't recall if it was Carter or not but somewhere I saw that the radio and heater were originally painted crinkle brown. My radio doesn't support that theory.
