I guess restoration and sale of historic aircraft involves much higher bugets
so the aircraft guys are getting picky about what they are selling or purchacing. found this link which has some interesting definitions regarding Historic Preservation Terminology

with values climbing how long untill someone buys something being sold as something that it could reasonably be proven not to be. And it all ends up in a huge court case?
