Old Firestone Car Radio

This is a great old car or truck radio.  Im not sure that it works but as a betting person id say it probably does as its in very nice shape for its age. Im not sure if its 6 or 12 volt but im sure its researchable to any buyers. i believe it to be complete but am unsure as its before my time. Has a nice extendable antenna included with it and seems to be made for the radio.  The control box says air chief on it and just looks to be in nice condition short of a little rust  on the back where it sat somewhere damp at some point.A nice steel and chrome accented box with the iconic Firestone logo!  The radio knobs appear to be bakelite and turn nicely!  A very cool original radio!
