Columbus cromor - Mystery frameset

[Michum]

Hello, i hope that you are enjoying your easter holidays
I've came across this frameset, it looks beautiful and i have spare parts to build a nice bike on it but i would like to know what it can be before i spend my money on this masterpiece.
Columbus cromor
ITA standard
Giro d'Italia sticker
Everything tells me that it can be one of italian manufacturers.

I was thinking about f.moser or eddy merckx (the second won't be ITA support) but i can't find any model that would match this colourway
