Found a Firestone
 

Picked up a 7" Firestone yesterday for $15.
This is without a doubt the biggest pile of junk I ever bought.

Cabinet is completely rotted away, no knobs, I had hoped the CRT might be good but it's pretty weak.

I think it's a Tele-Tone chassis? the chassis itself looks pretty decent so maybe I can sell it and get my money back:D
