I got lucky and found the new archeology sword Zin’rokh (item ID: 64377). When I got it I found that earlier items I had transmog’d with the original Zin’rokh (item ID: 19854) were mapped to using the newer item’s model.
Additionally, I found that when I went to the bank and checked out the original Zin’rokh it now renders with the new item’s appearance. This was not the case before looting the newer version of the item.
There’s a chance that the old item had it’s appearance hotfixed in with the newer model, but it would be a coincidence to be sure.
Not so the OG vanilla appearance is the sword held in an inverted orientation so that it’s “point down”. You can go check the images on WoW Head to see the differences.
Oh I see what you mean, same model but held differently.
Just checked and my OG one is held like the new one, and I don’t have the new one. Guess it got flipped around. I guess it is bugged then, but I have no idea if its a “new” bug or an “old” bug, if that makes sense. Probably nobody has the original sword on Retail.
Edit: Some screenshots from Oct 2009 show a Zin being held in the “new” orientation, a full year before Cataclysm would come out and people would have the new Zin. Looking into it more.
Edit 2: Found a comment on Wowhead that says that the original sword became “up-side down” in 3.2, or rather, its now in the orientation that it and the new sword are held in. So its only held differently in Vanilla and TBC. Common consensus at the time was that the sword’s orientation was always wrong and they just randomly fixed it for some reason.
Take your own advice. I did my research. The original sword had its model flipped starting in patch 3.2, and the new sword uses the exact same model. No evidence to the contrary.
