The guy is a seller from Thailand, icphysics, I think his Ebay name was. Anyway, I've been following the development of his Vader helmet for the past one year and I know for a fact he started off with a recast of a Rubies Supreme. His first offering had the tell-tale signs of a Supreme, i.e. neck flare, soft dome ridge, four nose ridges etc. The only thing uniquely his is the spiky mounting mechanism on the faceplate. I think he has been making improvements to his faceplate to accurize it, but the base is still the Rubies Supreme. He may have recasted a different dome now, though. I don't know but it looks very much like Portumac's to me, especially the dome flare.
