I believe the early Deans were made in the same factory as the ti Konas, by Sandvik. The cone stay ends, I think, would confirm this is a SAndvik frame.
The geometry might be slightly different to a Kona, or it might not...
At that price I'd take a punt.
Dean are still making ti frames in house, and bloody lovely they are too! Slightly overbuilt but the geometry is spot on!
Go on! You know you want to.
