This is an older thread by Kirill: the most cogent and subtle discussion of the origins of Qaddara.
The one in question in this thread looks newer to me and Iranian in origin, rather than Caucasian. I cannot ID the mark, unfortunately; it likely holds the key. However, the configuration of the fullers and the metal decorations of the handle push me to the "Iranian" side of the Arax River.
