I have a Gios compact as well. It has the same seat cluster, cable routing and dropouts, but it is yellow, supposedly from 88 (it has a 40th anniversary sticker), and made with Oria RANF tubing. I don't know the difference between the pro and non-pro models, if any.

There are a few Gios catalogues on Bulgier's site. Here are pics of mine. Btw I have seen electric blue (of course), red, gray, chrome and now light blue (yours) Gios Compacts...
