Re:
That sounds like a 1994 Kilauea, but if this frame is Tange Prestige Concept Tubing, I'm struggling to see the bulge at the bottom of the Seat Tube where it joins the Bottom Bracket. There may be slight evidence in picture number six, but a shot in daylight or more straight on may show it.
I'm also looking for a crease on the inside of the Chain Stay, as models lower down the hierarchy did not have this feature. Again, a picture detailing this or maybe in the daylight will help identify this frame.
It sounds like you'll need to scrape away at the paint to see a serial number! As I said in my e-mail, this will only date the frame, not tell us what model it is.
