Does anybody know anything about a Motorola 21C8?

I found this set for sale on an online auction site for a very high price. I loved the look of it so I talked to the seller for a while to try to get some info. The story doesn’t really add up. He said it was repaired at a local antique shop. Do any antique shops repair vintage televisions? He didn’t know the name of the store. The listing was just one low-res photo posted twice with a filter on it. It seemed like the only way I’d have any idea if this thing really worked was to buy it and drive 6.5 hours to see it. He agreed on a slightly lower but still very high price, but he would not change the listing price. Then after waiting a day for a response, he says he’s not doing that price. So I say okay, I paid your initial asking price, but now he says he’s canceling that and asking more.

So obviously I’m done dealing with this guy. It’s like pulling teeth and I have serious questions about his legitimacy. But… I really liked the TV so this is a big disappointment, but I can’t find anything on it except for a service manual supplement. I figured I’d find a photo of one from an owner but I can’t find anything.

Does anybody know anything about these TVs or maybe just happen to have one for sale? I’d still love to buy one if I could but it’s clearly a dead end with this guy.
