Burlington Route Caboose Water Container

Another piece from my husband's collection. Not sure what the proper name for this is, but I believe that it is a water container that was used in the caboose. Stamped "Burlington Route." The soldering has come way along one side of the top and I think it may be missing a cover or lid, but otherwise it is in pretty good condition. I've seen many similar ones in restored cabooses at such places as the Colorado Railroad Museum, in Golden, CO.
