This is a large 11X17 carpet and is definitely a sarouk with the small blue weft. My question is what type of sarouk? I guess my question comes down to the age. Is it old enough to be a ferghan sarouk, and if not a fereghan sarouk, what would it be?

1950s sarouk / fine arak rug. not farahan sarouk or feraghan, just sarouk / fine arak.

Thanks to both of you. I should have added the carpet has very closely cropped pile. From what I read the sarouk or even fereghan sarouk pile got longer as they transitioned to mahal, etc after 1900. Would the low cropping make a different decision. Fereghan's were also low cropped, but single wefted so I'm not at all thinking along those lines.

Thanks

No again, I know without a doubt that is not a fereghan, and of course I'd like it to be a fereghan sarouk.
One of my problems the terms are so misused. I see more marketing at times than description. From what I read there is no really definition of the type you named it, but a mismatch of styles. I am really not trying to talk myself into something, just trying to ask questions

Thanks
