Probably. But it looks lie a pretty good one.
If it is a gen, then I tip my hat to Vac and DSN because I can't spot the difference.
I would not buy anything of any value from Ebay, it's just full of scammers, nobody abides to the rules, and if you pay via Paypal, Ebay just wash their hands of any claims reported. Just far too dodgy for my liking I'm afraid.
But hey, that's just my opinion !!! lol
