Dunno...looks like a DBR (diamond back) downhill bike with a McMahon front end...old school, Horst Link, aluminum framed (not a good thing) long travel race bike. Any old aluminum downhill bike is suspect to not last much longer if you or he plans to ride it. Could be Chinese made, which most of this era were, but maybe not the more I look at it. Someone else could chime in here. The tubes are way fatter than most anything I have seen. Please supply better pics of the fork front to back...way cool old sus fork.
