From the inscriptions on the bastion, it is deduced that the gun was cast in 1549 at Ahmadnagar from bell metal by Muhammad Bin Husain Rumi.

Apparently a inscription on the gun recording that fact was erased by Aurangzeb, who substituted the present inscription stating that he conquered Bijapur in 1686

The unusual feature of the gun is that its muzzle is shaped in the form of a lion head with carved open jaws as if devouring an elephant (depicted between the jaws)
