Hybrids Body ID and Head Confirmation

I bought a doll off Mandarake that had enough authenticity markers to prove legitimacy, but no info on the sculpt or body besides the Crobi head plate. After looking, I'm 95% certain I've got a Yeon-Ho with a damaged company face up, but have no knowledge of if there were older sculpts that might look similar he could be instead. The head's resin also isn't quite a perfect match to the body as far as yellowing goes, and I've found what I'm assuming is a Volks imprint several places inside. No ideas which Volks body though! So I'm turning to those who have been in the hobby longer for help with confirming and elaborating on my identification.

Relevant bits that might not or can't be captured in photos: the body is single-jointed and he's roughly 61cm tall with the head and body together.

Part number is XY3, I think! It's pretty worn and faded, though.
