Help needed identifying shamshir wootz blade

[ariel]

Physical existence of a Safavid swordmaker named Assadullah ( var.) is suggested by the famous episode of a helmet and by the existence of Kalb Ali, who signed his blades as " son of Assadullah" and was referred to as such by various sources.
Forged signatures of both are encountered on the blades from different countries and different centuries.
Khorasani's assertion that "Assadullah" was a sign of high quality bestowed by the guild is easily refuted by a plethora of junky blades with that ( often illiterate) signature.
