Here's a couple from WWII.
My dad picked up a nice Walter PP with a holster during the war. On the way back to the US aboard ship, someone who knew about the gun got into his duffel and stole it. He never did find out who, lucky for them as my dad's nick name was "Brute".
Another Vet I know well, he's 87 now, brought home about six Lugers from the War. He slowly sold them off to buy washing machines, stoves, water heaters, etc. after the war. They are all gone now.
This same man also has a German watch with a .45 bullet hole right through the center of it. Since he carried a pair of .45's, you can guess how the hole got there!
Lock and Load!
