I'm holding the best source about Hungarian swords,
Kardok by Lugosi & Temesvary, besides I'd visited several collections in Hungary. While the design looks very closely to Syrian, this could be late court sword for lower rank nobility. Both Hungary and Poland adopted turkish-style sabers, often fitted with turkish to persian blades. The epitome of such sabers was during the 16th-17th centuries and they mostly lost favour as fighting swords by the beginning of the 18th century. Early style Magyar saber however, remained as a mark of status for nobility, usualy highly decorated, like this one

The small stone fixture on the pommel is hungarian motif, so it's possible.
