I think at least one of them may be authentic...
The hardware and fonts look like my BV from A/W '01 - '02:
My bag was bought new from NAP and even though my partner purchased it, I know it was from there because I had picked it out and knew he was purchasing it, because he disappeared into the room with the PC in it, to buy it and appeared, grinning, a couple of minutes later.
I also saw all the NAP paperwork and packaging after it arrived via DHL (and unpacked it, personally) and it was definitely from them.
I have purchased many times from NAP since then (probably 40 or more) and have at least 30 of their black boxes (some of the less expensive orders didn't come in black boxes, hence the discrepancy), so, I would definitely know if it had come from somewhere else.
TBH, I don't think he would, or could, have bought it elsewhere, anyway, as even if he had wanted to, he didn't have an eBay account until a few weeks ago!!!
I also noticed that they must have only had one of them on NAP at the time he ordered, because after he ordered it, it had sold out.
As you can probably see in the pic, it is undoubtedly authentic, as the leather and quality in general are amazing.
The only difference in the hardware between the two seems to be the 'ring' that attaches the zip-pull to the slider, but I think that could possibly be down to it being the woven leather version.
Incidentally, here is a link to the A/W '01 - '02 show on

You can't see the exact bags in question on there, but you can see similar, more exaggerated, ones and at least one with the square cut-out holes in the handle.
Giles Deacon was the head designer at BV at the time (he was sent there to modernise the house) and as you probably know, he is quite directional in his design and this, no doubt, accounts for the differences in fonts and hardware from BV's norm.
If you look at the show, you will also see the BV logo illuminated, in red, behind the models and you will see that it is similar to the fonts on both bags.
