Just pick up this book on the King Tiger, this is the best color, detailed book I've seen, comes from Japan, 96 pages, about 500 pics, I'd say 90% or more in color, close up pics for great detailing on both the Porsche and Henschel Turret. Pick it up from Dragon models, they have one also on the, Panzer II, Panzer III, Panzer IV, Hetzer and Elefant/Ferdinand.

Sample pics below.
