This is a fantastic and truthfully quite rare African antique. Made by the Nupe of Bida, Nigeria. I believe it is likely from the very early 20th century. It’s hard to pinpoint a timeframe on this type of thing. It could even stretch into the 19th century. Heavy etching and reppousse work on both the bowl and it’s lid. The brass is worked very thin. Over the years the shape of the two pieces must have shifted a bit because the lid doesn’t like fit perfectly inside the bowl as intended. You can get one side in easily so that it looks great for display but in order to get the whole thing fit perfectly into the bowl you have manipulate the rim a bit. If you wanted to take some time you could probably reshape it with your fingertips. It looks nice as is though and plenty good for display. There is a small hole in the side of the bowl. It is possible that the final/handle has been replaced at some point. It fits loosely. The piece bears the sticker of a Los Angeles antique dealer. Based on the sticker the dealer specializes in French antiques. The French did have a presence in Nigeria in the early 20th century so that may be the connection with the item coming out of their shop. The shop has been closed for around forty years. It is possible this piece was in the Cigna Insurance Companies corporate art collection. I cannot confirm this but it came in a group of items i purchased at auction. At least one of the items in the lot was deaccessioned by Cigna. The vessel is roughly 9” tall including lid, diameter is 8.25”. Ships ASAP!
