Never seen it before.
Looks a bit like an Epiphone Embassy Standard IV from the nineties.
But with Alembic pickups?
And is that an extra jack output near the arm cut?
Could be anything. Needs some paper work to make it legit.
The seller is Bunny Brunel himself. The output jack is the same as on his later Carvin signature model.
Look at his other listings. He's selling one of his Carvin signatures and several of his ESP signatures, which I think are still being made.
I'm confident that it's legitimate. I also think that Uwe needs to jump on it. It may be even rarer than the Leland Sklar signature. For all we know, this could be one of a kind.
