Couple of interesting notes...
Infantryman with M1 Garand, but still wearing a "doughboy" helmet. Didn't think they overlapped.
Several references to YB-17, even dated to 1942. Thought they droped the "Y' (experimental) long before that.
Somebody climbing a ladder on the waist of a PBY carrying a ".30 calbre machinegun", that looks like a Lewis gun. I didn't think we deployed those at all during WWII.
Any others?
