The other day I received a catalog from this company:
Military Issue : War Books, DVDs, Models, Figures and More.

There is just amazing stuff in there...reproductions of just about everything you want, from all sides of the war.

I have another one that I've been holding awhile because it has such great rare films of the era (or about the era) as well as some other miscellaneous stuff:
Military-WWII-Nazi-Soviet-Propaganda Videos-International Historic Films
