Here's some of the pictures I took while at APG.
this is about half of whats inside.
Big huh.
This is said to have hydraulic drive
a couple of panzers, III & IV, I think. These two both had some armor cut away and you could see inside.
And finally the big momma.
Correct me if I'm wrong. It's a Jagdtiger. Very hard to see from this picture but someone took a couple of shots at it.
