So;  the corpse with Antiquated Set / Dusk Set seems to appear if you defeat Manus - either through the darkened Oolacile event by doing Ciaran's questline, or post-lord vessel and doing regular Oolacile.

This is possible as early as defeating Gravestalkers at Sif's grave for the pendant; you don't need to darken Anor Londo, or ring any bells.
