Checking my own units it paradoxically appears that the early units did not have the "HPK-49GPLUS(B)" raised lettering on the back, while later ones did (e.g. I have 2 units from 2012 that do have this and several from 2006/2007 that don't). Presumably "HPK" is for "HP Kinpo", but just a guess.

We puzzled over that mystery earlier, and concluded that even 2017 serial numbers exist. You posted in that thread, so you should have known.

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.
