I think Jim is right in suggesting this is likely a trade blade in the style of Eastern Europe or Austro-Hungary, commonly used in Arabia or the Caucasus

I had a look in Eduard Wagner’s Cut & Thrust Weapons (1969) and found a number of similar 18thC blades from the Habsburg monarchy, with the initially hollow ground blade followed by two fullers. But these were either straight cavalry broad swords or curved hussar sabres. The sabres illustrated in the book are more curved with a more pronounced hatchet point, and fullers end in unequal lengths.

Identification is further complicated, as Jim mentions, in that the etching is very worn and indiscernible in the photos. But it suggests that the blade had been used and was intended to be recycled.
