On the Guerciotti frame, I don't know what tubing it's made from, no transfer. If the seat tube diameter is 27.2mm, that would lean towards 531. I'm not sure what the ID of Columbus would be.

Weight could be a clue. Also sound. If you build on it, stiffness would also provide a clue. 531 is super light, and it has a rigidity to it.
