What do I have here?

[bigbuckeye]

Hello Gentlemen,

I was just given this Luger last night. My Grandfather brought this back with him from WWII. Other than that, I don't know anything about it and I want to learn as much as possible.

Any comments would be apreciated, but I definitely would like to know the following.

Why the double date stamp? Was this originally built in 1914 and then rebuilt in 1920?



Thanks,
