Is my Luger jammed?

[Enoch]

Figured I'd post an image of the proof marks (right term?) in case anyone was interested. By the way, if anyone wants to educate me re: those marks and provide details re: what each one actually means I'd be very grateful. I realize I can get that information via research but if someone who knows would just tell me it would be so much easier. Yeah, I'm a little lazy

Also, my only other thread on this message board is from a few years ago when I was considering selling the gun (not considering that anymore, wound up selling a vintage Gibson mandolin to get the money I needed at the time) but, again, for the curious, there're pictures of the holster and magazines there. The thread is entitled "My Dad's WWII Luger..." Skal!
