Handmade metal Spittoon?

This piece is a very well crafted item that looks to be handmade .  It is crafted of two different pieces of metal. I am not certain what either type of metal is but both are very precisely made and fitted together. One part looks to be some type of brass or copper and the other is what looks to be some type of stainless but am not sure of either one. Neither seem to corrode or rust but both seem to show a very nice " patina " and looks to be made quite a few years ago. The piece is very solid and does not bend or cave in when pushed on or hit upon. It would take quite a blow to make a dent upon either metal surfaces.

    There are on marks or identifiable patterns  or stencils. The  bottom is not flat and would normally stand up very well by itself but has the bottom knocked or bent in so that it can stand by itself. There is no lid nor any type of cap that was attacked or one that served by itself as a cover.
