Zenith Bakelite Tube FM radio

A little rusty, but it works just as it used to. Bought this from a antique store, and, because he thought it was junk because it didn't get signals, he sold it to us for 10$. I brought it home, looked on the back and saw that detached green wire. i screwed it in, and it worked fine. i didn't mean to swindle the antique guy, but fair's fair.
