I wonder the same thing about a lot of the so-called "vintage" stuff. For a long time, back in the 60s, 70s and into the 80s, much of the now sought-after items were considered worthless obsolete junk, and were sold for pennies on the dollar at hamfests or worse still, tossed in the trash. Then the "vintage" craze caught on, and the formerly worthless stuff began to take on value, often culminating at the equivalent of pure gold. The collectors back then were mostly middle aged, with financial resources that allowed them to pay the sometimes exorbitant prices demanded. A lot of nice older stuff was saved from the landfill by this relatively new interest, and the older equipment held its value. I can remember back in the mid 60s my dream would have been to own a 75A-4, but then the going price was about $300, beyond the means of my meagre finances at the time. For almost a decade the receiver held its dollar value, but its price actually came down as the value of the dollarette continued to deteriorate. Finally, in the 1980s I was able to pick up a couple of A4s at $200 and $100 respectively, but they needed hours of work to get them in satisfactory working order. Now, at the most recent Dayton hamfest, I saw several A4s and the price averaged about $800, although I saw one priced at $500 something. People are still asking $1200-plus for A4s, and a lot of other vintage equipment is likewise priced high. But now, those middle-aged hams of the late 60s and early 70s who were beginning to take an interest and rescue the equipment that was headed for the landfill, are in their 70s, 80s and beyond, and there is no wave of younger hams or collectors following us to continue an interest in the old stuff. As the older generation dies off, who will be left to preserve the vintage equipment left behind? Will it once again become worthless old "junk" to be tossed out when the owner dies and the next generation cleans out his house to make it attractive to the real estate market? Or will a new wave of antique (by then the stuff will be well past 'vintage') radio enthusiasts once again resurrect a lost art and rescue the stuff from the landfill?
