Antique Indo Persian Islamic Shia Muslim Sword with Arabic Calligraphy

Antique 19th century Indo Persian, Islamic, Shia Muslim ceremonial all-steel sword in the form of a straight, double-edged medieval Islamic sword.
The entire broad blade is superbly etched on both sides with Arabic calligraphy, possibly verses from the Qur'an, a serpent, and the figure of the mythological demon "Div" (دیو).
The hilt has an elaborate pommel with an integral cross guard, down curving quillons shaped like stylized mythical dragon heads, and a pair of langets with silver koftgari work (now mostly gone).
