Inherited Krieghoff Luger

[marksf]

My father recently passed and this was in his safe. I didn't even know he had one, but if anybody could tell me some history behind it and a rough idea of what it is worth I would really appreciate it.

I am guessing the magazine is different because the S/N do not match the rest of the pistol and it has a marking I cant quite figure out but it has a "2" below the marking.

Also, it seems to me that all the small pieces with the 2 number on it are 90 and the S/N of the gun is 590.


Thanks in advance
