Hi, Very happy to welcome you to Shaktipeethas.org. First of all, thanks for your contribution.
Yes, I accept that the location of Shrinkhala Shaktipeeth at Pandua is a question of debate. It is considered to be present in West Bengal, Karnataka, Gujarat, Orissa etc. But, as far as I know, the exact proposed locations are only Pandua (West bengal) and Kigga (Karnataka). I accepted Pandua on the basis of two important points.  It's previous name is Pradyumna, you can confirm this from any reference of ancient Indian geography.  The Sakta Pithas, by Dines Chandra Sircar
which is the most authentic book on Shakti peethas also supports Pandua.
As you are a resident of Kolkata, and your mother tongue is Bengali, you certainly have an edge to us. We couldn't freely communicate with the local people in Pandua and what we learned is only from few people who responded to our efforts
What I can confirm is Shrinkhala peeth is at Pandua, but not the exact place of it.
As you are telling that you have photos of Hazrat Shah Masjid
suggesting it as a previous Hindu temple, please upload them. Another request, can please tell about MELA TALA. We heard that it will be held in that place every year on Maghi pournima. Is it true, if so, can you please give more details on that.
