Is this a Persian Kard?

Scabbards were the first thing to go due to the fragility of their wooden core, and were replaced at intervals during working life of any bladed weapon. Shaping a new scabbard for the blade did not differ from making an original one. Silver cladding might have been original or new because thin silver was also damaged as part of its exposure to the rigors of daily life. As a matter of fact, a perfectly intact scabbard of an obviously old bladed weapon ( like yours) suggests replacement, IMHO, or careful storage ( museum-like conditions) from the moment of its birth.
You got yourself a very good and fully genuine Kard, it is unquestionably authentic, but full originality of its composing parts cannot be proven. It is not a defect but just an inevitable consequence of its age and active usage.
