Okey dokey, this is what I think we need:
Signs. Steve, can you ask t'other half for accurate translations please. I'd ask my dad, but we've just had a bit of a falling out due to my damn brother 
1 x Test Chamber
1 x Medical Officer (Medizinischer Offizier)
1 x Commanders Office
1 x Guardroom
1 x Radio Room
1 x Munition Store (Munition Speicher)
5 x No Entry used for Regen Points - 1 spare! (Eingang verboten)
1 x HQ (Kommandantur)
Various x German propaganda Posters (how many did we have last time?)
Maps:
8 x A4 sized maps for organisers to annotate and hold on to
2 x "Display maps" for the HQ's - not as big as last time - say, A3?
I'm going to make up some signs as well for the field telephones on a wood backing - so they can be reused (its something i've wanted to do for a while) - plus some other random signs as takes my fancy. Really want to make ones we can reuse 
Any other ideas, please list 'em.
When we were a Kingdom it was run by a King
When we were an Empire it was run by an Empress
Now we're a country we're run by a..........
Note: I'll check all the German as last time it was all a bit 'wrong'.

No entry = Eingang verboten!
Test Chamber = Versuchskammer
Medical Officer = Medizinischer Offizier
Commander's Office = Kommandantur
Guardroom = Wache or Wachstube
Radio Room = Funkraum
Munition Store = Munitionsspeicher (one word with a joining "s", so you end up with two "s" in the word)
HQ = Armeeobercommando or Oberkommando or Kommando (depending which force)
