Probably a case of quantity over quality, but if I were in the area I would take a LOOK, just in case. Just ONE or TWO TOTL receivers or TTs amongst the pile would make the deal worthwhile, financially. Probably none there, but it wouldn't cost to look and be sure. The rest could be "dumped" in any of many ways.
Once I saw a hand-lettered sign in a shaky hand in a shop window, advertising old furniture. It had been there for a few days, and I almost ignored it, but just on a hunch, decided to check it out. Was an old lady with nothing impressive in her place at all. Oh, well... almost...
I chatted with her a little, and when I said I was hoping to find something carved or antique, she explained that she was selling the stuff there in order to make room to start pulling her other things out of storage and sell them next. She took a stack of photos out of a drawer, and the first one was of a hugely elaborate, carved wooden desk nearly identical to one I had seen a year or two before in the Hannover Antiques Fair, priced at US$40,000!

She said she had already sold that desk to a good friend, for $500. She knew it was worth more, but "they were a good friend!" ...but if I liked stuff like that, she still had plenty more nice pieces in storage that I might want!
Turned out the lady's husband had written scripts for Vaudeville and Hollywood stars for decades, and then run a fur business (selling, renting and storing fur coats for celebrities and socialites in Southern California). They had also owned a small hotel for a while, IIRC. He had made a lot of money, but had died years before, and she had gradually used up most of the money he had left her, and didn't want to keep paying storage fees on stuff she would never actually live with again. I ended up buying an entire moving-van full of stuff that she had had in commercial warehouse storage for years, and she also gave me a couple boxes of old correspondence, including dozens of letters from some of the most famous Hollywood stars. Some of the signatures on those papers alone were worth real money to collectors, but to her they were just "old papers" that she had hung on to only because they had been her husband's. Some of the stuff I put up at auction at Sotheby's, and made thousands of $$ on it - overall it was an extremely good "score", from an umpromising notice that I almost ignored!
You never know what something is until you check it out and see for yourself. Most of the time you may be disappointed, but the guy who keeps panning eventually finds the most nuggets. Someone should go and at least check out what the guy has.
