The 2nd offering is a legitimate Bianchi, specifically a 1982 model. It is Italian, as opposed to being one of the early Japanese manufactured frames. As noted, this is a mass produced mid-range model with tretubi Columbus Sl,at best. It may be even lower grade tubing, as tretubi SL models,would typically have down tube shift lever bosses during this era., though European Bianchi models do not always directly correlate with American models. Also, it is another repaint. Again, I have no appreciation for European market conditions but in America there is no way that I would pay even close to the asking price.
