Tiffin Box perhaps
 

Just back from a small "antique fair" which was more like a vintage tabletop sale frankly.... you can tell I was not impressed! However I came away with two items at an attractive price, the one I am posting here being what I think is a tiffin box comments as to exactly where it might be from and what it actually is are welcome.

.. or perhaps not.
 

A friend was over yesterday dropping off a sword, and having similar interests to myself in ethnographic miscellania we had a chat and a good go over the piece. Probably not a tiffin set as there are not enough sections, three is usually a minimum, and there are signs of heat being applied to the slightly bowled base of the larger vessel. Not an industrial product but well made by hand, and a few telltales of patching to fit. Tinned by dipping in the eastern style.
We concluded that it was more of a canteen or mess kit,.. but for who?

narrowed down
 

Well my online searching is narrowing down the possibilities. It looks very like something from traditional Indian brass ware often referred to as a milk-pot. But, they have a flat bottom and no internal tray unlike the one I have which has a bowled base and an internal tray or division. Pictures below of an examples of a "Milk Pot". Still searching!
