Lovely looking frame there, and you were very fortunate to find an unbuilt one.
Perhaps nit-picking, but they didn't do size 18 and this looks like an 18.5. Also I don't think they used the 'Moron' name for the tubeset until 1995. The 1994 catalogue doesn't seem to mention it.
They said the Moron tubeset was customised Tange Prestige, but the 'more on the butts' description seems to fit Tange Prestige Ultimate Ultralight perfectly. It was a 9-5-9 tubeset, so it had 0.4mm butts when 0.3mm butts were almost universal. But it was still a much lighter tube than Tange Prestige MTB, which had 9-6-9 top and down tubes. Perhaps what they meant by custom might have been that it had Ultralight top and down tubes and Prestige MTB everything else.
It would be interesting to know what the frame weighed, and also what your riding impressions of it are.
