Agreed Northern India or the area
Now about
"It was described as an "Ivory handled short sword, brought back from Tibet".
but it doesn't look Tibetan to my eye".
In fact, nobody said that it was made in Tibet but brought back from.
I won't be surprised if a soldier (British) brought back this dagger from Tibet.
Maybe the dagger was used in Tibet, maybe it was just for sale in an Antique shop. I saw Persian daggers for sale in Damascus and Yemeni jambiya in Cairo...
