Atala was a moderate sized manufacture in Milano, I think. But, most of the frames I've seen were relatively mid quality.
Yours seems to be the top of the line.
I think your paint job is what is called "Cromovelato". Tommasini made quite a few of them. I don't think I've seen an Atala with the cromovelato, but that will give you a good search term.
I'm seeing some marked Atala Professionisti, and Atala Super Record with the cromovelato paint.
You've done a nice build.
