I'm a huge Vantage fan but I've never seen one of these either. It doesn't resemble any known model lines that I'm familiar with. It's a strange mish-mash of elements, can't seem to make up it's mind whether to be an electric or an acoustic.
I'm almost tempted to say that this started out as an acoustic and was modded to be an electric. I have seen a couple of ads recently for
acoustic Vantage Avengers! The head stock is the 'squid head' design though. But no electrics.
If the logo is anything to go by, that version of the script does look to be MIJ rather than MIK. Hard to tell from this one pic but I think I can just make out the solitary "V" at the top too. So at least the neck seems to be the real deal.
