Suggestions on country- leaning towards Iran [решено]

My first request. I'm finding the Numista database and search engine very powerful but my linguistic skills and research capabilities have their limit.

Any suggestions as to direction to search for this coin. Purely based on the style os the script I am leading toward 19C Iran but have found no visual match. Any suggestions ? Coin weighs circa 11g , 26mm, poss. silver

British India, silver rupee of the Bengal Presidency, fictitious RY 19 fixed, mint name Murshidabad, 1790s

There are several variations of this coin listed in Krause.

Thank you.

As a historical note, many Indian rupees look similar to medieval Iranian coins because the Mughals came with Persian roots, and then early on some of the British India coins were similar the Mughal-type coins.
