I'd guess your item is from the Kashmir region of India , strictly from it's peacock/paisley & flower motif , dhoppy ...
(I'd also guess that the bird atop your item is a peacock)
Since your item does not seem to be oxidized much & is unpolished (by you) , I'll give a guess that it may be tinned (coated with a thin layer of tin) .
You can test for this metal by using a clean (& fluxed) piece of solid copper wire (held by a vise-grip) heated over a flame till it's quite hot ; touch the hot copper to the 'silver'surface of your container (somewhere on it's under-base , perhaps) .
Allow the wire to cool & look for 'silver' (tin) deposited on it .
Tin melts at a very low relative temperature (silver does not) .
As others have said , I'd say that this item was used to contain : rosewater , oil or ghee .
