Anybody for one more round of what might this be worth?

I would say $250 at least if working. Cool jewel!
Thank you! I'd like to hook it to power but kind of unsure which wires. There's a red wire which I'm thinking is power and two orange wires that seem to connect to one which I'm thinking is the ground but I think there is a yellow and a black wire as well that could be ground. The others go to what looks like a gaggle of speaker wires and a plug. Where it gets kind of interesting is the antenna. It looks like two wires come out of the radio and into that resistor and then that goes into some kind of splitter as well.
I do know about CB's is I'm pretty sure you don't want to key up the microphone without an antenna. And then also generally the antenna has to be kind of tuned to the CB?
