The knoted gun

In a town near Sweden there is a statue on a stone pillar which is a gun… Not just any gun, the nose of the gun was knoted neatly. No one knows how the nose has a knot in it, in fact, when the people found it, they didn’t know still how it got like that. It said on the pillar it was a revolver once used in world war 1 and one of the enemies found the revolver and used it to kill enemies in a brutal way and after ww1 it was abandoned and its gold colour rotted away leaving its naked metal skin.
