I'm showing both the original helmet as well as the transmogrified helmet to be usable by Death Knights.

Original helmet: https://www.wowhead.com/item=51127/s...rgelord-helmet
Transmogrified helmet: https://www.wowhead.com/item=40820/h...readplate-helm

Look at the transmog though - it's warrior Tier 4.

Several items in the game have the same look, and some have a similar, just different color scheme.
WoW is known for recycling a lot of assets.

It looks like:
Gladiator's Plate Helm (Warrior's only)

What it should look like (as it's written on the tooltip):
Hateful Gladiator's Dreadplate Helm
