Luke, They would be. But considering their size ...
During my PAO career, I was assigned for a few years to the UH-1Y/AH-Z helicopter development program office. We had on hand the 1/4-scale wind tunnel models of both aircraft. After the wind tunnel work was over and the sensors and tape removed, they were painted to look like the aircraft and mounted on pedestals for display. They went to a few industry days, conferences and trade shows until folks just got tired of dealing with them as just decoration.
They were really cool. But they were really huge and somewhat heavy. I think they used mahogany or something. Anyway, when the program office moved to another building, we lost the space to display them, Bell Helicopter didn't want them and no one knew what to do with them. I tried to move them over to the museum -- but they had no space for them. I even offered them to the National Air and Space Museum (got to meet the rotorcraft curator), they weren't that interested in them.
As I recall, the NASM would have been interested in them if they were still configured as wind tunnel test articles rather than having all that stripped off and turned into display models.
Eventually, they lost their indoor storage and the last I saw them, they were under a tattered tarp behind the test hangar. They were starting to delaminate from being exposed to the weather, so I didn't look at them anymore and moved on. They've probably been hauled off to the landfill by now.
So, they probably ended up in a dump, too. Heavy Industry, be it automotive or aerospace, is not, generally, nostalgic. Once something has served a purpose, off it goes. They don't even save their cool concept vehicles.
