With "even 2017 serial numbers exist", I was merely pointing out that your "no later than 2015" isn't true, which makes the 2006 date you proposed for the CNA628 one no longer a necessary conclusion (and improbable, given the other signs of a late unit).

You're right, I was focused on the 17 issue. I agree the CNA628 unit certainly does appear to be from mid-2016, later than had seemed. Tim's announcement in late '15 was regarding parts availability, leading to end of 50g production; perhaps that was the last buy of those end-of-life components, but the supply actually lasted for mfg. runs well into 2016.

It remains curious why HP would add that "HPK-49GPLUS(B)" legend late in production...
