Sorry, I couldn't see the groupset name in your photos.
But as I said, from 1995 the Chorus seatpost was ex-C Record but with "Chorus" on it.
Record seatposts are immediately identifiable, because of the saddle clamp bolt: it's hidden on seatposts from lower groups.
No problem, always good to learn new things about the old stuff. ;)
If you know where to look, Record always had something which distinguished it visually from lower groups...
PS That other group is Athena... except the seatpost! :0
