An Apollo 17 recovery image of the top of the CM, ap17-S72-55888 from ALSJ.
What is the structure inside the red polygon (drawn by me)? Is it the "flowerpot parachute attachment fitting"?
Left and right of it are two drogue parachute mortars. The white sling with the crane hook is the sea recovery sling used to lift the CM aboard the Ticonderoga recovery ship.
Yes, that is it.
Labeled as such in this image.

This picture shows that fitting between the mortars.

There's a picture (not labeled though) showing the parachute-stowed configuration. I highlighted the first part of the risers in green.
