I'm afraid it doesn't look like a Gios to me - the cut outs on the BB and the drop outs don't look right - a real one looks like this (it ain't for sale). The frame details suggest a 70s/early 80s frames and yet the decals and forks are 1990s. Headbadge is riveted and not a sticker too. http://imgur.com/Or5WX.jpg
