Ahoy Vince,
No new compartments announced as of yet.
If your planning on modeling the boat with interior, here is some info
for you.
I just picked up some PREISER of Germany 1:72 scale Panzer crew
and Panzer maintentance figures. They are beautifully sculpted and
their uniforms could well pass for u-boat crew uniforms. Many
difference poses and they would look great inside the compartments
offered by CMK.
Also picked up RoG figures, sadly, a little static for my liking.
Warrriors also makes 2 sets of figures, a tower crew and a gun crew.
These figures will surely bring your u-boat interior to life.
Have a nice day and happy modeling,
Joe
