serial # seems a little low for it to be authentic? who knows, just speculation.
After spending 90 on an authentic v2, I probably would just try to find a good clone if I bought another. As much as I like it, hard to justify that cost. Also, my center post (copper) is a bit mangled from the heavier gauge wire. had to put in a longer screw (1mm longer) to ensure good contact these days.
As someone said earlier, if it works, the price was right, and you like it, who cares? Only bummer is potential misrepresentation of the product.
