What an amazing story, thanks for sharing.

I don't know how familiar you are with the American Old West or if you know the name Wyatt Earp (if you've seen the movie "Tombstone" from the early 90s, he's basically the main character). Earlier this year, the shotgun that Wyatt Earp used to kill the man who murdered Earp's brother, Morgan, was auctioned and sold for $375,000.

Not saying you'll get that kind of money, but there would seem to be a strong market for weapons used in famous murders. I can't imagine they come up for sale very often.

Good luck with whatever you decide.

Amazing, I'm currently reading the story of this assignation and investigation.

As I recall, the Swedish police had never encountered metal piercing ammo before, and didn't know what it was.
