All are single pivot.
Actually, Chorus went through some design changes as well. Those look like a later version of Chorus monoplanars. The earlier version of Chorus did not have the same pronounced curvature above the brake pads and also had a flatter front edge in front of the brake pad bolts.
I'm copying a quote from member bianchigirl from
this old thread which shows the earlier version (and her added cobalt nut), and some more notes on Chorus vs. Athena differences:

another difference is the use of the afore mentioned white 'O' ring and the white plastic covering on the wheel guides. the heavier pad mounting area is a Athena detail I believe.
when the rounded brake pads came into vouge I am not certain but I believe it was with Athena.
these look the most like what i would call a
real chorus
FWIW these came on my '88 Super Leggera, so I know for sure these are original Chorus, well aside from the capnut
