Ok so have an opportunity to get this mid 80's Masi Prestige for nice price. Has campy RD, shifters, Mavic rims, signature on stem, looks to be mostly original but what is throwing me is the lettering on the downtube. Looks to be AIANAN. Have to look at it better, only got a sneak peak. Pic is not of good quality. Anyone ever seen this model or name on the down tube before?
