Highest serial numbers

[AndiGer]

Dear HP calculator enthusiasts,
In the museum's collector's corner we have as a good reference a table of earliest serial numbers (so far)
http://www.hpmuseum.org/collect.htm#earliest

With nearly any calculator we have a year of discontinuation in its details.
What I can't find anywhere is the HIGHEST serial number - and therefore youngest produced calculator - of the different models.

Maybe I missed that and somebody can point me to such a list.

Or do we have to start a competition for that?

What I can say for sure: I don't own a calculator produced in the year of discontinuation mentioned in the description details.
