Nice! I've never seen one fully chromed, but there are lots of things I've never seen. The group looks to be period correct except for the rear wheel, cluster and rear derailleur...

Are the brake levers slotted Campy or something else?

There's something bent on the front derailleur, btw, the curve should follow the shape of the chainring...

we need to see the fork crown in more detail, too. The correct vintage and model can be extracted from the fork crown and lug details.

Are there dates on the rear derailleur and the crank arms (circle or diamond with a number in it)
