I can answer it for you.

>Pre Mughal
Information is relatively scarce. That didn't stop bronze age TW, but it still wouldn't be as useful as going Mughal onwards. You'd have to really innovate for ideas to distinguish places beyond the easy to digest regionalism divide of Northern India being Iranianized (or literally Iranian conquered - then later Turk conquered) and South being more indigenous.

>Post Mughal
When I was at my university I remember in the library a dizzying amount of books of India arms and armor from the colonial period. I only scanned one, I'll offer a few snapshots of it. Goa is established around the 1500s which means you have at least one European option - Brits and French establish themselves later into the 1600s, but this is also peak Mughal so you are best off waiting for Aurangzeb to die and the 18th century chaos. This is when you have a dizzying array of principalities and little states, the British and French in full, the Rohilla (Afghans who had settled in India), the actual afghans invading, the widespread use of armor still (though I am not sure if the europeans did, but I'd assume they'd have cuirasses sometimes) with musketry and so on.

Okay - but why make 18th century India TW as opposed to 18th century Europe?
