Hi Robbie.

Thanks for the history lesson. Seems that my frame is closest to the "Blue" group but may never know for sure. I bought the frameset with red paint and no original decals, except for a Columbus decal on the seat tube. As far as I could tell, the red paint was original as it was the only color overspray inside the BB lug and on the steerer tube. But on a 25+ year old frame, can't be absolutely sure it was the original paint. Previous owner was the second owner and obtained it from a former Cat racer in the Midwest. He's convinced it's a Cinelli Corsa which had a brief run in the mid 80s and only sold in Europe. The only difference from the Super Corsa being the seat lug. It's Columbus SL tubing, no swirl in the butting so not SLX, so it's definitely mid 80s. Incredibly light for a vintage frame, lightest of all my vintage Italian frames (Masi GC, Cinelli SC). Ashley sent me a message that I should look into the Cinelli Unica, haven't found much on it yet.

The research continues...
