As this seems to be Atala week, I thought I'd put in a couple of questions. Some of you may already know this bike as my Clunker 100 contender, or "the bike formerly known as Sandra". It wears Atala decals, but I'm having serious doubts as to whether it really is an Atala. I've searched the web for confimation, but to no avail. As I've come to really like this bike, I'd like to know what it is, and maybe even restore it to its former glory.

• is it an Atala? If so, what model? Year?
• if not, what is it? Any ideas?

I've not yet been able to find a serial number. It doesn't have one or it is well-hidden. The seat post is 26.6 mm. The BB shell measures 68 mm, the dropouts are from Gipiemme. The parts are from all over the place, the only stuff that I think might be original are the BB and crank set; both are made by Thun. There's a code on the adjustable cup: 34 8 (I think).

I'd really appreciate your insights.

This is the way it looks now:
