Thanks, interesting story. I found the Danish language version earlier but couldn't interpret it apart from the dates and a few words.

Looks like the gun in question was brought in from England (likely) in accordance with the last line or two of the story.

I think of the opening scenes in Out of Africa where Karen (Meryl Streep) and friends are elegantly dressed and firing double shotguns:)) Those were probably English guns for the upper classes back in the day.
