but from what I've heard and understood, JLC has no interest in divulging production numbers from decades ago.
We're left to extrapolate based on the data points we see in reality. For me, e-B*y has been about the best source for voluminous data. Even some of the rare Atmos I iterations have shown up there.
I stopped tracking the auctions because it was just too time consuming. 5000 of them (took about an hour per week to quickly peruse each auction to see if it was a rare clock, rhodium, etc) was enought
