This is a great read. Thanks for posting.

Its a point well made, but I would factor in one more point with this example. Ball is a popular (particularly in the US) manufacturer today and that would have to, you would think, create a market for vintage examples.

Didn't many of us start collecting Heuer because a Heuer or Tag Heuer was a watch we got when we were younger, or our parents had one? I guess there are exceptions such as UG, which seems to be startlingly popular today without any real modern presence, but I would think modern marketing spend has some impact on vintage popularity.

That said, the correlation between scarcity and value is fascinating - and your example proves that point.
