The part you describe is an original, made with plastic.
A metal cover was later used by Airstream
Then Zip Dee came out with a modified cover, so that their awning would rest on the roof, not the cover. After a few years, the mold for that metal cover broke.
Then a fiberglass replacement became available that matched the Zip Dee design.
The round vent cover hole is supposed to be covered with a fine mesh metal screening to keep the bugs out.
That screening, can easily be added.
