[Rivkin]

If my memory does not betray me, Zand is a family that ruled in the second half of XVIIIth century. The only dynasty of farsi (lori) background, spent zt least the half of their rule fighting turkish lords-Qajars and other semi-independent leaders. Lost to Qajars in the end of XVIIIth century.

Now I am no specialist on the matter, but first of all I always found it to be problematic to definitely distinguish between some of Qajar and Zand pieces, they are often done in the same style. The similarities are substantial, with an exception of touristy or very low quality revival pieces. Why I think this work is Qajar? The image is kind of soft and gives me the feeling of XIXth century processes - etching or something else. Indeed the style is reminiscent of Zand-Qajar, but I do think it is Qajar and btw not early Qajar.

Now with the blade I am even less of an expert - my take was somewhere in Azerbajan, north-south. Ham is probably right (?) with his Dagestani attribution.
