I have converted about 10 flayed ones from plastic warrior models and bought an additional 8 metal flayed ones.
I have 7 metal pariahs which seems to be excess, as they can not fit any of my army lists.
I have 4 destroyers and looking for more.
I have 3 Necron Lords one with Resurrection Orb and one with Destroyer body. I have built the destroyer body with magnets and I can interchange it in to a Necron Destroyer if I need.
I have about 80 warriors only 50 built. I will convert about 10 into Necron Immortals.
I have 12 scarab bases any of which I have not fielded yet.
