I think this is about a 78 or so Super record that has been repainted and had some later components put on it. All the frame features we have seen are consistent with an earlier Super Record. The fork crown and BB cutouts were changed by 79 so this is earlier than that. Recessed brake mounts didn't show up until 80 or so though so this has been modified to accept them. It should also have a head badge not a decal and the painter may have used the wrong Columbus sticker. I have found the Gios Blue group on Facebook to have some really knowledgeable Gios people.
