Not bad, I think it's an early superhet design hence the decent performance. There were a few G.E and Westinghouse sets that used that same setup as that Greybar.
At least whoever you bought the set from got the message about the price somewhat and reduced it to sell. One radio I looked at about a month ago, was a Canadian Westinghouse model 80 also from 1930 but it was a TRF. The seller wanted $150 for it and it was listed for two months at that price in spite of the fact that it needed refinishing, has mostly ST style tubes, and is in unknown condition electrically.
Now the set has ended up in a local junk "consignment" shop for $350, well if it didn't sell after two months on craigslist what makes these chuckleheads in the shop think they can get $350 for it if the current owner couldn't get $150? That shop has exactly the same clientele that Craigslist has, in fact they post a lot of their crap on C.L to try and sell it, they don't think that someone will recognize it? The first thing anyone is going to ask is that magic question "Does it work?" the answer is of course going to be "No", unless the dummies try plugging it in, they they will say "Oh" and walk away. Nobody is going to give them anywhere near $350 that for that thing for the same reasons that nobody is going to give them $65 for a Guild "Country Belle".

P.S It also has a price of $170 written on the chassis with a felt tip pen, that was likely the price the current owner paid for it if not less.
