About 10-12 years ago there was a photo going around the internet of a storage shed in Vietnam that had burned. All around the ashes were laying about fifteen to twenty burned Thompson sub machine guns, ruined.
I do believe several members of that firearm forum wanted to cry.
I have read that the Egyptian Government still has thousands of Remington Rolling Blocks and Remington single action revolvers in their arsenals, all in pristine shape.
Who knows what other goodies are hidden in back alleys and dark places in the world.
More than that; better than a pickup truck load. Most, but not all, were the later WWII M1 and M1A1 guns with the bolt cocking handle on the side rather than on top as on the early Navy and Marine guns.
Now we know what was in those boxes in Raiders of the Lost Ark.
