Good stuff. I wish I still had the demilled 37mm round that kicked around the household goods when I was a kid. I suspect it came from one of the great uncles who served in WWII. One fly into Normandy in a glider with a 75mm pack howitzer. Those guys didn’t get jump pay like the rest of the guys in the 101st; they deserved it, those gliders were no picnic.

As the Germans retreated, they left equipment behind like every retreating army. My dad “captured” a railroad train which included an entire carload of Mausers. Of course his unit moved on, so he could keep only the one.
