Ah ha! it must be '96 then, i knew it was one of the two, it was once a stars and bars (or a similar fancy design) but it was resprayed when it belonged to its first owner, the respray was done by pashley; and it had new decals at the time. I think, though not for sure it was built by tom teesdale???
No, I would doubt it. Tom Teesdale made the Hots up until 1995 and the catalogues always listed his Hots as being made of Tange Prestige. He still builds frames (and uses 853 nowadays) http://www.tetcycles.com/index.html
but Altitude Cycles seem to have gone out of business and I haven't been able to find out anything about them other than that they were in Chico California. They built the Hot and Ku frames from 96 to 98 and the custom Caldera in 97, the painting being done in Washington by a firm called VeloGraphics.
Obviously the adoption of 853 for the Explosif for 1998 must have hit the Hot trade and that was the end of the line for custom Konas unless you count the titanium frames. You'll find a few in this site, but I'll just show you the one that justly won Kona of the Month in January owned by Kase1983 and an extraordinary frame owned by Mr Zero that has the fattest tubes I've seen on any steel Kona of the retro era, as well as a biovalised down tube, presumably as some kind of experiment. Note that both have top tube cable routing, indicating 98, whereas 97 was a hybrid, tt for fm and dt for rm.
