Hmmm, if that's chrome on the head lugs under paint, I'd have to wonder if this color scheme is a repaint. I mean, why chrome the head lugs to begin with if one's going to paint over them?

I hope you can bring them back to presentable shape for the repaint. Chromed lugs didn't get to be common on Colnagos until the early 80s. In the early 70s they were rarely found outside of show bikes.

From the pics, the post looked like Campy's first-gen Super Record two-bolt post, the one with the flutes, reduced wall thickness and modified cradles.

The new pics show a high level of workmanship for the production frame that it is. Those head lugs are plenty thin (as are the diamond reinforcements at the brake bridge) and their shorelines are near-perfect. Take lots of pics when you get it down to bare metal; believe me, you'll be glad you did!
