I just emailed Colnago-America (as the info@colnago.com did not work for some reason) so I'll let you guys know what they say if they can help me out.

If it is a Colnago Sport what year would it be? I would love to try and find some pictures on the net to try and find some similarities. And it would kind of make sense if it is a Sport since I live in Canada If what you are telling me is true about these frame types being used in the North-American and European markets we might be closer to ID'ing this bike.

Thanks!

ps
Just found this site ( http://www.foxgalleria.com/bici/sport/index.html ) which has similar markings like mine. Possible match? This one is an early 80s sport however on mine notice the fact that it has two waterbottle carrying bolt sets which leads me to believe it is late 80s... Thoughts?
