Nurgley Exhausts, hip piece pinned in place. Replaced a number of the cables and the Nurgle Flesh (i.e. GS) hides some other naff cables.
The shoulder plates (and head not shown) have been attacked with a dremel and the one plate had a little GS added.
And with the shoulder plates and head blu tac'd in place...
Obviously quite a lot left.
I am also looking to rebuild completely the conversion beamer, for a start I don't like the look of it but it is also a crap cast with wonky struts.
