What do you see here?
I think there's an issue with this derailleur. It seem more obvious when in hand, but would like to know what, if anything, you all see from the following photos:
This is an Ebay purchase. I'm considering returning it but want to make sure I'm not overreacting and seeing things. My lack of specifics is to avoid influencing anybody's opinion or eyesight
Thanks!

Cage looks twisted. On the plus side, it has red "speed pulleys".

Funny you should note the "speed pulleys" as that's why I bought it. I will use the pulleys while a buddy, who has the correct ones, will use the rest of the derailleur. Assuming it's not messed up.
To which cage were you referring? Main body or pulley?

Both cages look slightly bent to me and in a twist causing the two pulleys to be out of alignment to each other.

Not just bent, but twisted, as @thinktubes said. Those pulleys look they are rotating on very different planes, which I think would be problematic. Not that those C'dA derailleurs shift all that great anyway.

The bottom pic looks way better to me than the first, even so the lower pulley bolt is either long or missing a lock nut and not true through the cages.
If a locknut is missing it might straighten that out some but cages seem not true either and I would assume many are not after the time and miles they get.

Cd’A Photo from Disraeli gears. The pulley cages look straight and pulleys aligned in this photo. Campagnolo Croce d'Aune (B010-SM) derailleur

In addition to the two (different sized) pulleys not rotating in the same plane, it looks to me that the cable clamping screw is both bent and has the internal hex stripped out.

Thank you all for you observations and responses.
Yes, I was also thinking the jockey cage plates were bent. When I noticed that most here agreed, I decided to take the derailleur apart to confirm. Yup. Both bent; the rear plate was the worse of the two.
One washer was missing, but l had a spare. When I put that spare in to see what things looked like the bend was obvious. All fixed now, plus I learned how to dismantle/rebuild a CDA RD - which is good practical knowledge to pass along to my buddy when it comes time for him to put the correct set of jockey wheels in there.

Many years ago I found a square of 1/4" plate safety glass. Stashed that away and it makes a good reference plate for things like this. I don't use it often but is handy when I need one. Even for rolling axles to see if and where they are bent.

Another vote for bent inner and outer pulley cages. Rear pulley will not run in plane with the front one.
There also appears to be visible witness marks on the inside of each cage, indicating greater-than-usual chain wear.
You can try to bend it out if you take both cages off, but the accuracy of straightening the outer one will almost certainly affect the inner. The inner is more likely to bend and twist to conform to the much stiffer outer plate.
