There's another avenue no-one's brought up yet that I think is worth consideration: Your knowledge of what those hubs are was hard won and the result of years of study and practical experience. Personally, I would save the hubs and only build them up if I found corresponding NOS parts to make an entire NOS wheel. And then further, only to mount to an entire NOS bike of the period. I would then, display, store, give to a museum or sell said bike at a profit commensurate with the torturous amount of time, blood and sacrifice it would've taken to find/build such a beast.

And it would all have started with my interest and the ensuing education I gave my concentration to. There will always be someone inspired more readily by a NOS piece than a used one, to follow in your path and I suppose that that's the point: To pass on your interest to someone else.
