Now here is a third example of a sword with the odd, inset pommel decorations. This one was confiscated after being put up for auction illegally in Poland, and the would-be seller was arrested. The seller had "no explanation" of how the sword came into his possession...
The article says "preliminary assessments by archaeologists show it is original... probably from the 10th-12th centuries". This date range seems a bit off the mark, so that doesn't exactly inspire much confidence in the claim of authenticity...
Altogether, a very suspicious set of coincidences...
