I'm looking at a Gios frame a friend has for sale, and I have some questions about which model it is.

He believes it to be a mid-eighties Super Record, and that's what the decals say, but here are the frame details, some of which seem contradictory:

1. The top ends of the seat stays are not engraved - Professional stays have GIOS at the top.
2. There is no FD hanger - Professional has a braze on hanger.
3. There is no engraving on the head tube lugs - Professional says GIOS on the front of the HT lugs.

So far, it says Super Record. But:

4. Rear dropouts are drilled - a feature only found on Professional?
5. Rear brake cable guide is internal, on the top of the TT - again, only found on Professional?

The bike has been painted - blue, but not the official cobalt blue, and we're pretty sure that the forks are from a Professional - chrome (but painted blue), sloped crown with GT engraving. The bottom bracket looks like this (GT cutout, with 4 cutouts at corners) except that the cable guides are underneath, not on top of the BB.

So - I look forward to hearing from those with more knowledge than I about this.

Thanks.
