You get this rare vintage original 1973 old cutlass radio model number 7936143. It’s untested I’m not sure how to test this one. Looking through the case covers it looks very clean like possibly like new on the inside. Yep I just opened and took a pic for you. Looks almost like new inside. The tuner knob and presets and the volume knob they all function perfectly, but I don’t know how to test it under power. Missing dials and not sure if these knobs are original? Free shipping. Ty.
