There's no sarcasm. You posted 3 or 4 relic swords, which are in my opinion, not from the periods they are supposed to represent. This blade is obviously authentic. In peripheral museums that don't have arms and armor curators there are all kinds of things on display, with all kinds of wild attributions.
The blade you posted is narrow, suited more for an officer's sword than a munitions grade weapon. Any of those brass hilts would work. Good luck!
