In India the Maharaja's were Hindus and the equivalent Muslim name was Nizam, as in the Nizam of Hyderabad. Could be a Nizam's case? I have a 16 Bore Manton double Howdah rifle that has a gold oval with the initials "WAKP" I inquired with the Indian for Guns sight and they said it probably was the Wazir Ali Kahn of Phulra and later became the Nizam of Phulra.
