He's made from an old CSM Lord model, with the arms replaced by a bolter and a Chosen axe. The bloated head is from the old Chaos Sorcerer model. I had that bit laying around forever waiting to use it for my Nurgle forces. Still have his eyes to finish and some spattered gore to add to him.
In other news, I have got to get a better photo taking set-up. I'm off next week (WOOT) so I'll have to go purchase some materials to make a light box. That should help. I also want to finish at least one of the Nurgle Grinders as well. I have a reenactment at the end of the week so I can't lollygag!
