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).

I am pretty sure about this. My 49g+ had a broken key (it was already a warranty replacement of a defective unit) and had to fight with HP support not to have a third 49g+. They accepted replace with a 50g, which came without box but with vinyl pouch. It was may 2007.
I purchased the spare unit two years ago on Amazon for a fair price (about 50 eur), it came without box but with canvas pouch and USB cable. Appeared to be absolutely mint.
