Great books!!!
2012 Catalog:
Dented Rick and Floydsky works inside (but I'm not sure there are other zealots). Really good builds.
STK technicanum: probably the most comprehensive book about Imperial and Astartes tanks!
Exploratorum II: more and more and more Space marine Chapter!
Is a volume I out there?
