Is no doubt that in the Armory palata Persian swords of the 17th century. There are documents to prove it.
If Kirill Rivkin says that in Manouchers book the swords represented are only second half 18th and into 19th centuries, then I would presume that comment to be compellingly accurate knowing the level of his knowledge and experience.
It seems, after rereading the remarkable article by Oliver Pinchot, that dated examples of 17th century shamshirs are relatively uncommon, thus often the method of recognizing them is primarily by the character of the blade itself. Apparantly Mayer (1962) was able to identify a good number of Assad Allah blades signed, but these all were apparently AFTER the reign of Shah Abbas I. As his reign was c. 1587-1628 (Stone) then these still would fall into 17th century.
Mayer (opcit.) notes that despite the questionable historicity of the name Assad Allah, the name was associated with fine sword blades in Persia by the late 17th c . and notes dated blades supporting this.
I am inclined to agree with your view that Assad Allah was likely used in the sense of a 'brand or quality imbuement, and that in time there were many copies of lesser quality produced to capitalize on the name as a marketing ploy.
