What is this Ektar Lens?

[Fotoguy20d]

I thought it might be fake too. But, if you look at the glass closely compared to an f4.7, its clear that it's smaller. The more I think about it, the less interested I am (its attached to an anny speed on ebay) in picking up yet another anny to get at this lens - doesn't seem likely to be a WF type. If anyone's interested, I can point them to the auction.

Are there any more pictures of the lens? Seeing the glass from an angle could tell if it's a gauss design.
