Oh, no disappointment. I am very glad to be getting this help from such knowledgeable people.
It had what seemed to be ages of tarnish.
That photograph I put on shows the entire marking, the only mark on the item.
Here is a view from the side, showing that it stands on a flat bottom. The entire thing seems to have been hammered from its upper side and also pressed with some sort of narrow tool just around the outside of the inside (upper side of) bottom (where it curves upward from the bottom), and it has this same tooling along a rounded V-shaped channel or groove that extends up each end of the bowl part and to each end of the item. In a little of the tooling in the channel toward the higher end of its bowl (I mean the end away from what seems to be a handle end of the object) there is just a little coppery appearance; otherwise, it seems to be silver everywhere, even the edges.


And here is a picture from overhead, with a circle around that only place where it is marked, on the upper side of its flat rim near what seems to be a handle end.
