Carl,
Let's see some detail photos. It wasn't that long ago a frame was sent to me for paint/restoration that was believed to be a Colnago. It was "confirmed" as such by more than one bike shop to the owner. When the frame arrived it was immediately obvious to me that it was actually an early 70's Ron Cooper frame. They can be confused. Photos will help a lot. I have 4 early 70's Colnagos and the same in a Ron Cooper, so I'm pretty familiar with them.

Being an enthusiast of classic bicycles, as we all know, requires detective work to research history. This is just what I have been doing with my early Colnago Super. With the help of Ray Dobbins and constant internet research, I finally found a hot lead. Ebay Item number: 130087330917 offered a major clue, though regrettably, a prior owner had molested this vintage frame by having internally routed top tube cable guides, front changer braze-ons and shifter braze-ons added. Had they known the rarity, perhaps they would have found a later Colnago instead. In any case, the main notable features of this frame which lacks a fork is the head lugs. These lugs lack the small point on the sides from the semicircular feature on either side of both head lugs. Also notable is the clover on the lower lug that is larger than the smaller clover on the top lug. The British seller explained that he concluded the built date by features rather than number stampings.
This find may have finally enabled an answer to be know. If any list members have additional clues to share on this early Colnago, or related thoughts, it would make for some great reading.
