I indeed do recall... in that conversation it appeared a unit from week 1 of 17 had been confirmed via the warranty website. In this case however, the unit starting with 7 does not have the "HPK..." legend, which seems to be common to all late devices. I've concluded it's early, but until more definitive info. is available, I'll grant you it's not proof.

The OP says he owns that one since 2007, so the CNA715 unit is definitely an old one. 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).
