I've found quite a few sets here, but that's mainly due to the fact that my landlord/employer is a hopeless packrat who squirreled away over 200 during a period of over 50 years and then gave them to me when he found out I collect them ( I'm still a long way from bringing them all home, I haven't even seen all of them yet). I have brought home some nice curbside finds and junk shop sets, but I haven't seen anything older than 1950 here. At that time, there was good reception of the stations in Memphis, about 50 miles away. There are still houses with those really tall antennas in town, and I know of a few people with older sets still in daily use.
