Colnago Mexico 1979

I have not been able to find any info about the frame, or a similar one.. Its a grey Colnago from the late 70's / early 80's. Condition of the stickers would indicate this is the original paint. The tubing is crimped once from both sides, it's not the Columbus Gilco tubing used in later colnagos, but the columbus-sticker is missing (although you can clearly see where it once was).

The build is my own, so components are not what originally came with the bike.
