A fancy peshkabz, a call for help on translation and thoughts on provenance

[GePi]

Hello,

I have been looking for years for a high quality persian style peshkabz and finally I was able to acquire one (two actually), although it took a kamikaze-like approach to get them.
The blade is very typically persian, with a ladder pattern and nice chiseling, 18th century I would assume, but the dress is not what we usually see.
The grip scales are hollow and made from silver and the scabbard is heavy silver with wood lining and elaborate chasing, gilding and niello with three niello inscriptions.

The auctioneer listed the provenance as Dagestan, which I don't believe is plausible, I tend to think either central Asia or simply Iran.

The cartouches are two makers' marks and what I assume to be the owner's name.

I am very interested in what you all think, and if you can again help me with my flailing attempts to translate (I know you are around kwiatek )
