You may have already seen this. In Hartford Conn. during a police gun buy back a woman turned in a rifle that her father had brought back from WW2. It was just sitting in her closet and she wanted to get rid of it. IT was a German Sturmgewehr 44, the original "assault rifle". The two cops running the buy back realized what it was and told her that it was worth $20,000 to $25000, and that it belonged in a museum. They didn't take it from her and told her that they would talk to the ATF for her so she could give it or sell to a museum.
