Caipha Morarg's hat - where do you get one?

[Urauloth]

Artwork of Caipha Morarg shows him with a pattern of helmet I don't recognize. It isn't a standard Mk III design, and it doesn't seem to be one of the common Death Guard variants either. It has a medieval look I'd normally associate with Dorn's legion, but I assume there were any number of Forge Worlds out there making helms like this for the crusade.

 

 

What is this? Is there one in a kit somewhere? The most similar thing I can think of off the top of my head is the Grey Knight kit, or the recent Imperial Fist upgrades (without the wreaths). I think there might be something similar in one of the Blood Angels squads as well?

 

 

If there's one out there, I'd love to get hold of one. Also if anyone knows any lore I'm missing about it, do let me know.

For the first piece of art, perhaps a Bladeguard helmet with the top bit removed would work? For something close to the second piece, the Iron Warrior mark 6 heads have something similar.

Closest ones would be one of the IF head Kit from Forgeworld.

You would need to remove the laurels and middle strip of the helmet.

Reminds me most of the company champion helmet but with slits for breathing instead of the the cross pattern on the left

I think I might have cracked it, a combination of all the above suggestions made me think to go looking through the Black Templar range, and the Primaris Sword Bretheren have the closest match I think it's possible to get.

 

 

There's a couple like this, and one even has vertical slits instead of a cross pattern, but this one has the line of studs along the brow like the helm in the artwork.

IW mk6, would have to trim the bottom.

...wait a minute.

 

Was this in the Plaguemarine kit the whole time, and I just didn't realize because of how decayed it is?
