Dan already guessed it ,..it's a Nishiki Alien SP designed by Richard Cunningham
Got this one yesterday and now thinking what to do with it,....it's in a bad shape,.... :(
Except for the rear derrailleur it looks completely original.
Here some pictures, it's looks better on the picture then it really is, there is some serious corrosion underneath the paint.
Might want to strip it from the paint , polish and then clearcoat it,..
Will tell some more soon about my connection with the Nishiki Alien and some history about the Nishiki Mountainbikes
