It's definitely an interesting specimen, notice the flame-like palmettes in the field. These sure appear to be the archetypes of those which appear in that rare group of Kurdish rugs, where similar ones can be seen.
Also another palmette that appears there, those ragged edged ones with a floral motif inside sure look like archetypes for those found in many NW Persian/ Caucasian long rugs as well.
The symbiotic relationship between Classical Persian Carpets, like this one, and many of the somewhat later rugs made in NW Persia/Caucasus and those we now call "Kurdish" surely needs to be further explored.
However, the chicken-and-the-egg corrundrum this raises is not so simple as that. No doubt the designers of these Classical Carpets were privvy to patterns, designs and icons used by earlier generations of weavers.
The entire question of Timurid carpet weaving and the lack of any known examples is another perplexing subject that just lately seems to becoming investigated and might yield some insights into the derivations of the designs found on a carpet like this one.
