here are the detail "changes" for '80, both of which are evident on your bike:
1980
- Fluted seat stay caps engraved COLNAGO and straight seat stays (no longer biconical shape)
- Brake bridge with square boss for recessed brake bolt

it also looks like yours has nutted brake calipers, where they "should" be recessed.
almost looks like the previous owner has used brake cables for shifter cables, so perhaps they used shifter cables for brake cables? you might want to look into that.

I also have a Super from this same year range. very nice ride, i love it a lot.
