Believe it's a Modello 800, but could be a higher model number than that. Likely made in Mexico, although it's hard to distinguish from what I gather. The Mexico variety is prone to dropouts and bb shell cracking / breaking after a certain amount of stress. I'd say beware if there is no "Made in" sticker, unless the price is hot. They ride nice, and have great geom, but it seems inevitable that the brazes were overheated in Mexico...?
