Tha Super's of this vintage used Columbus SL tubing. As it's a repaint I don't think you can take much notice of the decal set it has fitted.
I've got a very similar Colnago as yours. Mine was used as a pro racing bike for a Belgian team and if originally had aSuntour Supurb Pro groupset but Colnago's were fitted with a wide variety of components and your build specs are quite appropriate.
I love the colour of your frame and it will be a very nice riding machine.
Here's mine:
Thanks, and nice bike! Do you know what PIU is an abbreviation for? Could you order any of their frames with this option? I've also noticed that there are substantial differences in where the cable routing enters and exits the frame - seems they were playing with different routings for a few years there. The seller seems to be pretty adamant that this frame is a Mexico - I'm curious now if they did a Mexico PIU? What do your headtube to toptube lugs look like - are they triangular or more trident-shaped? It seems like the Masters of this vintage used the trident lugs, and hers has the triangular ones. I sent an email to Colnago asking for any info on that serial number, but nothing back so far.
