Nick speaking,

That's the Space Wolves 13th Company Geigor conversion complete. In the end, I decided to magnetise his head to give me both options, a Chaos head for when I use the model in 40k and the actual Geigor head for 30k games. The sword conversion ended up going really well. Turning that metal left handed sword into a right hand one was very tricky, but it came out well and was well worth the effort. Hopefully Abaddon won't be too upset that this guy has stolen his sword!
