Every single one of you guys has pointed out at least one incongruous feature of this frame. It has a plain-Jane flat crown, though I've spotted the stay arrangement before, just now too. The paint is similar but not quite as intense as one I just saw on the net. Some, myself included are evaluating all based on its being EL/OS, looks like it not sure, need to meas. the OD of the tubes. Supers overall that I've seen received better treatment, much better, even the Super lable looks plain.

Not suggesting it's a fony. The International is a prime example of Colnago's being all over the place. All of this is easier to reconcile if we were to know if it's from Europe.
Merckx for example had Euro-market models different from the US. This bike has more exceptions than it does typical features.
