Persian and Qajar, yes but there is something about the traces of pitting on the blade that makes me wonder whether it is not wootz.
Since the blade will benefit anyhow from some polishing, why not give it a try?
Even the hilt an scabbard could benefit from some polishing & etching as they have been very crudely cleaned, so much detail was lost.
I would polish the blade with grits 1000-2000-3000 then try etching it for wootz.
I would also polish the hilt and scabbard, gently, with grits not lower than 2000/3000. Then blacken it with Perma Blue and polish out the high relief with grit 3000.
But it is not my blade.
