Ralph H. Baer Ft. Riley Kansas small arms display and ID challange

Ralph H. Baer http://en.wikipedia.org/wiki/Ralph_H._Baer
The father of the modern video game was was assigned to Military Intelligence during WWII and became an expert on military small arms. Baer returned to the United States with eighteen tons of foreign small arms for use in exhibits at Aberdeen, Maryland, Springfield, Massachusetts Armory and Ft. Riley, Kansas.
These are original photos from the Ft. Riley Kansas display I came across.
I thought it might be interesting to post these and see how many we could identify.
Some are obvious and some vey obvious (lables visable) to even me a novice collector. Some not so much.I would also be intrested if anyone has any additional information on these displays. How long the displays were in place? What became ot the displays?

PS: You may want to save the pictures in order to enlarge for detail.
