Just checked and it looks like I don't have it. The one I thought it was is actually blue and not exactly the same any way. I know I've seen that one somewhere and the only thing I can think of it was one of those random skin previews at the bottom of the one of the pages at original skin site.
The WayBack archived skin preview pages are far from comprehensive but you'd have to search through the entire XBMC, UnleashX, Evox and Avalaunch pages they did archive to see if it is there. But that probably wouldn't help anyway as the original listing didn't include any skin number.
I'm doing some more skin downloads sometime if, by luck, I come across it I'll post again.
