The brakes look like Athena to me
Now, why did I say 100% sure . Never a wise thing to do. I think you're right, with the straight line of the flat section rather than the curved line that the Chorus ones have. I thought I had seen later Chorus brakes like that too, but it's true that the early Athena ones (like 1993, for example) didn't have the name on them unlike later models. You've got to love that era of Campagnolo where they decided not to put the name of the groupset on almost any of the parts.
