I see sometimes on Ebay something that is unique but there is just not a wide audience that appreciates it. I remember a fixed freqency marine band receiver by P.A.R., Seattle WA. Surely there are one to three people who potentially would be interested enuff to save it, but it's not priced with that reality in mind. So what happened to it, when it didn't sell, at the owner's exalted opinion of its value? Or the military VHF receiver, 1950s, which i had never seen before, and i'm certain you had not, either? Well, my answer is, you can't be Horatio at the Bridge and be there to save everything. 

I saw an ART-13 at a recent Oregon hamfair. $50 and no sale. In Lesser Oregon you cannot sell an ART-13, RBC, BC-683 etc. at a hamfair.

Maybe, i'm thinking, a certain % of this material SHOULD  be crunched up or thrown into a volcano cauldera as sacrifice, to make the supply - demand more in balance. The only problem with that is, some last-of-its-kind survivors also get crunched.
