Since we are nearly completely off the rails for the topic, let me throw a couple things out there because I expect you guys might find them interesting.
This is from the same visit to the Littlefield collection as the Panther photo above. The WW1
Renault FT:
Interesting thing about it, pointed out by the tour guide, Armor and the metallurgy involved was still young when these were made. As a result, the plates were proofed before being accepted. How do you proof armor plate? Well, you shoot at it of course. Each panel on the tank had dings, top and bottom (and some middle), where it was shot at proof testing the plates. This is the right side plate from the turret (facing left in the photo above):
Thought that was pretty cool.
And on the subject of shipboard small arms, I was in the Navy in the late 80s, when I had my Petty Officer training (can't remember the exact name, everyone had to go through a class when they made E4) the Instructor was a ~25+ year service Master at Arms Master Chief. He told a story of when he was a junior enlisted, and the destroyer he was on was being decommissioned, and had been in service since WW2 (probably a
Allen M. Sumner-class, some of those served into the 70s).
Part of the decommission was the accounting for the small arms, and their transfer to wherever the Navy sent them when no longer needed on a ship that was destined to become razor blades. The guns involved were primarily Thompson SMGs and 1911 pistols. The problem they found, they had twice the number they were supposed to have. They went back through the paperwork, and figured out which serial numbers were originally issued to the ship during WW2, and ended up with a dozen or so guns that were not accounted for in the paperwork.
Long story short, after a bunch of digging, he found all of them were originally assigned to a different destroyer in WW2. That ship got sunk, and it turns out the survivors were rescued by his ship. Apparently when the crew abandoned ship, they took their small arms with them into the rafts, and when they got picked up, they stuck them in the in the arms locker, and there they stayed.
He joked about how tempted he was to take a completely untraceable Thompson home with him, but insisted he did not. I wouldn't be surprised if he and the rest of his group ended up with 1911s that as far as the Navy knows were on the bottom of the Philippine Sea.
