I couldn't find any English article about it but I think that story's worth sharing.
Some Polish guy has found perfectly preserved Walther P.38 and Lilliput in his barn during it's renovation. They've probably been hidden there since WWII.
You know what he did?
He called the police, and police has confiscated both guns. End of story. Guns are not legal in Poland. I wonder what you guys would do in his situation?
