I did indeed!
It turned out that it’s a Colner, not a Colnago. Colner was a sub-brand of Colnago which they created to allow them to enter a second team in races. It doesn’t quite have the prestige (or probably quality) of the real deal but it’s still a lovely thing with plenty of pantographs and nice details. The original Nuovo Record groupset (1981!) is in pristine condition. The wheels run smooth and true.
It even has a name engraved on the stem (was covered with black tape in the pictures) which I have taken over. She’s called Bärbel.
I paid CHF400 (£275) which I think was a good deal. I’m going to clean it up, probably repaint some of the details (ie the pantographs, enjoy a few retro rides over the summer and then probably sell it on to some crazy Germans next Spring.
