Ljungmann AG-42B bought at a local auction ($60, or $80 can't recall) circa '86. My first deer gun. It was sold as a "semi swedish mauser", and no one there had a clue what it was. I was surrounded by local, tough-guy, gun lovers when the action snapped closed the first time EVERYONE jumped back. Good times.
I wasn't home when the registration came into effect, and a family member registered it...it was a "torped overlsag" according to the registry.
