I picked up a Colnago Super this week and I’m trying to determine what to do next

It appears to be mostly original with some great Campy Super Record Pantographed parts! I’m guessing it’s a ‘77-‘78 due to the pat. Number on the derailleur. The stem has been replaced and is gawdawful (the seller is looking for the original, but it’s likely gone, but I have an extra Cinelli that might be a good placeholder), and the wheels have been replaced with Mavic MA3s. The paint has a lot of chips and scratches with rust, and the decals are rougher than they look in the photos, I’m afraid to even breathe on them. Also, the fork has a bit of rust pitting, but it might be salvageable with some evaporust and foil.
I’ve been looking for a Colnago to restore for a while, and I want to do it right. Unfortunately, at 56cm the frame is just too small for me

so I’m faced with a bit of a dilemma. To repaint or not repaint? Is it worth the money if I can’t ride it? To be honest, I absolutely enjoy restoring bikes, but will I get a return on investment? Or should I just touch-up the paint the best I can and call it a day? Or, lastly remove and restore the components (again, awesome Colnago panto’d Super Record!) and sell or trade the frame for one that is my size? I would love to hear your input BF members!Thanks in advance,Ian
