brain was Columbus' midlevel tubeset ,produced from Cyclex rather than the more sophisticated Nivacrom steels- this category of frameset's appeal will be for use as a classy user rather than as an high demand object d'arte to the collector. For a 2nd-tier Guerciotti of early/mid-90's vintage, I'd expect to pay *somewhere between* a figure of about $250-275 for a very well cared for but obviously used frameset with zero issues on up to maybe $425-450, for an unusually pretty/desireable & immaculately pristine , NOS frameset.
