That is an interesting thought. Do you really believe the demand for our vintage parts will be greater in 40 years? Who are the buyers? I have been to several auctions and buy out of vintage collections from collectors who have passed or no longer capable and need to liquidate. You or your heirs would be lucky to get .10 to .20 cents on the dollar. If no one knows what it is, you didn't, the salvage man gets it free. Just an opinion, but I have seen multiple times in the last few years.
