With regard to the little Olmo-- I have been doing some research and it may be Nuovo Sprint. The Nuovo Sprint came with Galli components and Alle tubing. On the other hand the decals look just like the Proffesional, but that came with Super Record and SL tubing.

And on Velospace HitOfMiss has what appears to be the same bike in a different color. He didn't identify the model though
