As a kind of thought experiment I wonder how being the new "owner" of this would be anything other than a terrible curse. It's not really useful in any way to most people so you probably decide to hawk it. You have the full might of the DoE and other government agencies monitoring for it. Let's say you somehow establish contact with a weapons dealer or foreign government agent. They are just as likely to whack you and take it to clean up the trail as any other outcome. There's basically no way to win, and no zero sum in this game.
