Well, ... HELLO !
I have a Friend I've known since 1995. She is 100% Finnish. Last name is Wirkkala, comes from a family of Lumberjacks and Timber Haulers in Washington State. She has a great sense of loyalty and resolve to always work hard. She calls it "SISU".

Can't tell you much about your Luger other than the "Crown Over Ms" have some sort of Navy issue heritage. The front sight is unusual to me also. The barrel does not have a step where it meets the slide, so I think not what it came with originally during WWI.
