This is a special model.It is one half of the Black Library Daemonifuge diorama.
Practically unreleased but being true to myself I tweaked him just a bit.
The original belt buckle was just like a standard Marine.
I overlaid it with a bit I cut off of a Grey Knight chest bit,also added a couple of purity seals.
I have finished the Knights portion of this army and are now getting to the really good stuff.
