I just purchase this 52 cm Colnago "Mexico" on eBay. The seller says that he got it from a collector and it is a "Mexico" built in 1979. In my reserach, the Mexico has rounded top tube and downtube but the Nuovo Mexico has the Gilco tubing ( a round tube that featured four distinct symmetrical flutes through the central section of the tube and resembled a 4-sided star ). But the supposedly, "The Colnago Nuovo Mexico was released approximately 1983 and available for only a few short years". On the photos, it looked like Gilco tubing pointing to Nuovo Mexico. Are the two names "Mexico" and "Nuovo Mexico" loosely used and interchanged? Any thoughts on anything about this? Also what do you think of the condition of this frame? I want to leave it as is and maybe do some cleaning ( any advice on that as well? ). Any other thoughts on this? Id love to hear anything that anybody want to say. I am pretty excited about it. Thanks.
