The good people of 2Velo have a copy online of a 1987 Atala catalogue. Your bike looks like a variant of the 'Corsa GS' frame set.
Thanks for a great tip! The picture above also proves that green fits nicely.The paint doesn't look bad at all and the metallic green is a rather nice color, IMO. You could just replace the GIOS stickers with an Atala set and call it a day.

BTW, if your bike rides anywhere near as nicely as mine, you've got a pretty good deal.
