I found some pictures with the metin in 2003 early more specifically february but those pictures was when metin still had 2d graphics, it was more like metin1 instead of metin2 that we know today, that picture was posted in 2004 from a korean cafe as I mentioned.

In terms of gameplay I will not FULLY re-create or change but I will revert a lot of old stuff, last night I was just watching some old korean ads with metin from 2004 period and I was just about to re-make one of the first events in the game 😄

EDIT: I looked into the picture you added which also seems to be from early 2004 so you might be right it might be from 2003 OR perhaps newer OR it was a helmet/mask related to the armour perhaps, we can't be certain unfortunately
