It's Aldo again. I've got two Atala from the early '60s, a copper 1960 and a silver 1962. Both came with Gran Sport derailleurs and Atala cottered steel cranks. Both have a metal head badges. The headlugs have cut-out windows in the shapes of elongated hearts, commas, kidneys, teardrops, etc.
Atala are easy to identify by the serial number stamped vertically into the seattube just below the seat cluster. The first 2 numbers will be the year of manufacture.
Hope this helps.
