I think that is a re-do of one of the odd blue "Centurion" Cinellis that we've seen a couple of. It's frame is nearly identical to those, except for the color. The fork is the same, very similar to the Super Corsa.

If you go to the thread RFC started here about the Equipe model, and look at the bottom, the orange re-do by CyclArt appears to be this same type of frame. Their decals are the only one's I've seen with "project" in them.

My educated guess is that both this bike and the orange one in RFC's thread were done by CyclArt, and were originally the blue "maybe Equipe's" that we see on eBay from time to time. However, on none of those blue ones, or this one, have I seen any type of OEM decal that mentions Centurion. They may be out there, I've just not seen one.
Just another question to be answered when we all meet up in bike heaven and get to speak to Gino. The connection is what we're after, gotta be one somewhere....

My theory is that when Cinelli sold to Columbus, some bikes escaped to hook up one last time with the Bianchi girls in town, and ended up milling about the planet.

And further, it's a pretty darn nice bike, no matter the proper purity of pedigree. It appears to be my size, and yep, I'd take it in a half a heart beat.
I'd strip it, paint it bright red, apply Cinelli decals, and go find a guy on a Super Corsa and race him. Then we'd retire for vino or a bottle of Fat Tire.

And Ofmega? I think their crankset was the nicest made in 1985. It just didn't match anything.
I'd love to have an Ofmega group...

I am so glad you didn't get that bike in Montana. I paid through the nose for that thing.
