I'm looking for an animated TV show based on King Arthur and the Knights of the Round Table. It came out some time in the 80s or early 90s. It centres around the Table and the Knights. All the Knights would place their swords on the Round Table. The Knights of the round table all had the same swords that were different from the other Knights. I think it was just a special black cross piece on the hilt.
In the intro they showed the building or rebuilding of castle Camelot. They lifted the Round Table into place with rope. It had magic and monsters like much of the fiction about King Arthur. All the Knights wore the same clothes and armor.
It is not King Arthur and the Knights of Justice or The Legend of Prince Valiant or King Arthur & the Knights of the Round Table" ("Entaku no Kishi Monogatari Moero Āsā") or Arthur! and the Square Knights of the Round Table or Camelot Enchanted Tales or Arthur! and the Square Knights of the Round Table
Out of all of these, it is most like 'Camelot Enchanted Tales'
