My daughter recently inherited this Luger from her grandfather (she got to pick first from his collection and has excellent tastes). The pistol is a byf 41 "Black Widow" with all matching numbers and a correct magazine in what I would consider Good+ to VG- condition.
This pistol was a bring back from WWII by my daughter's grandfather's step-father. There is no paperwork with it, but the step-father was a Brigadier General (Army Air Corps) so I doubt he needed any. Interesting man. He was a WWI ace w/ a Distinguished Service Cross from WWI (the mission for which he was awarded the DSC took place on my daughter's birthday). He was also the Chief of Staff of the 9th Air Force during WWII. I am trying to get some sort of solid provenance concerning the pistol, but all I have is family recollection (the General has been dead since the 50s).
