A very brief update (The Old World has been taking most of my attention). 

I got some psykers and servitors stripped of their old paintjobs and ready for cleaning. 

The psykers will be used as primaris psykers or astropaths as needed, I've not got enough to field the psyker battle squad. 

The gun servitors will be added to inquisitorial retinues while the tech servitors will accompany the enginseer.
