So I just picked up this colnago frame off of ebay a few days ago with the inention of building it up with at least somewhat period components. The only thing is I really am not all that sure what year it's actually from. A lot of the details and the general style of the frame seem to say it from the mid to late 80s, assuming the paint is somewhat original, but the fact that it has a threadless headset and 130mm rear spacing would make it seem more like late 90s if I understand correctly. Also the mexico model, which it does look a lot alike, especially the mid 80s Nuovo Mexico, wasn't available in the 90s from what I've gathered. Anyway, any help would be greatly appreciated, here are some images of the frame:
