Looking a bit harder at the last two, The next to the last one looks more like copper then Brass, I ran a search on Jinuu Copper and got lots of Science artitcles on stuff about copper, way above my head though, not sure if that is a connection or not. Let me make sure I see the letters on the bottom right. " Jiunn Maa " . The name and title seem Asian in origins, but not sure. Unless this was made to look old, I would feel safe at placing this item in the early 19th, but this is just from the looks and style The footed bowl was pretty popular in the Victorian era espically Late Victorian. Sometimes these thing takes time to find, years even may times you will be researching something else and stumble on the answer. As for the second one, it appears more pottery or ceramic like, maybe just the pics but doesn't look metal. This one really looks old, but that may not always be necessary the truth, extreame wear and tear can do a number, then the items made to look old. In this case, not much reason in making something look that old that usually has little value overall. This more happens when a name is one the item, Unless they wanted to make it look relic in nature. Either way the looks of this piece would say really old, but with no real clues to go one, this would be more like Folk Art, made and used by the same person sort of issue. If so maker will be almost impossible to conclude. Basically here you will need to persue more of the age issue. You did note that it appears to have a seam line, This would be a pressed mold issue, this would almost disclude it being a Folk item, that would say Manufactered for sale generally. So with all that you and I are probably more lost, just stick with it, Stay in the trade of Antiques and Collectible and the answer will come, let just hope Soom I would like to know too.
