Well as far as paperwork goes for the story I honestly don't think so as my grandfather passed away about a year ago but the story he always told us is as follows:

My grandfather served in the 12th armored division under Patton. During WW2 they entered a town (I believe in Germany but I don't recall 100% sadly) and were ordered to clear several houses by going door to door. My grandfather said he was "about to knock on the door to this one home when suddenly the door opened, a gentlemen who was very nervous said something in another language and handed him a towel which was being used to cover something". The man then Closed the door and that was all to the interaction. My grandfather was standing there in disbelief and looked down to see this holster with the Luger inside. (Pics to follow) my grandfather looked around in disbelief and brought it back to his tank. He says he has had it ever since. I've only seen it once or twice growing up and until recently due to him passing have been able to really look at it in depth.

So after doing some limited research (I am not a gun enthusiast but I do own several) I found this sight with the hopes that someone can give me a little history on the gun to really satisfy my own curiosity? So any help would be fantastic!!

There's several marking on the gun and I believe a date of manufacture. Also all of the numbers match each other including the two magazines. There are some very small insignias on one side that I cannot make out to well. Again any help would be great!
