name that Campagnolo rear derailleur (Athena Avanti differences)

preparing to put on an Athena groupset, I found myself staring at three Campagnolo rear similar-looking derailleurs wondering "which is which and what's the difference?"

In the photos they are marked, from Left to Right, "Athena", "Avanti" and unlabeled (just "Campagnolo")

The one with the groupset does not have a model marked on it. Just "Campagnolo". and it is the RH one in the attached pictures.

The other two (from my spares drawer) are marked "Athena" and "Avanti".

Now, I always understood that Avanti was kind of crap stuff and that Athena was better. But construction-wise they look very similar.

And then the unlabeled Athena (RH image) looks quite different from the marked Athena (the flange bit in particular, which looks similar in style to the Avanti but is a different shape.)

I don't have a scale here, so I can't weigh them to see if the difference is there but can anyone shed light on the differences here if any?
was there any evolution from Avanti to Athena or vice-versa?

The right Athena is an early one, 1991-1993. Campagnolo started to label the parts in 1995. So the left derailleurs are 1995 and later.
The differences between Athena and Avanti derailleurs are small, Athena is more polished.
Avanti is not crap, just the cheaper group.

I agree (I think) the right one is an early Athena.

The above is correct about the unmarked Athena being pre-95. If you do some digging, the circa 95 / 96 Campagnolo spare parts catalog is out there on the web (and I think I may have a copy on one computer or another around here) and can show you which parts the Athena has in common with the Avanti and which are different. There is probably a difference in the jockey wheels, probably the quality of the plates holding the jockey wheels (strength and flex difference) as they do look different in the photos, and the Athena will be higher polished.

I have a 1st gen Athena RD and it doesn't look like the rightmost's picture. Mine is highly polished all over and the upper jockey wheel configuration is entirely different.
