Colnago identification

About two years ago I purchased a second hand carbon colnago frame, and to be honest I find it a thrill to ride every time. I have tried to identify the model but not had any joy.

It is lacquered carbon with red fade outs at the end of the tubes with a gold band on the black lugs, white colnago transfers including ernst colnago signature. It is exactly the same as a carbitubo except that it has a single downtube and not the famous double. Forks are colnago engraved. rear drop outs are alloy.

I would be grateful for any assistance.

Cheers

You will need to post a picture of the frame/bike ...
