Beautiful old silverplated stand and dome to hold a serving bowl at the table or on a buffet - I love the globe shape, very unusual. I couldn't find any makers marks, but it's tarnished inside and out, so the hallmarks would be hard to see.
It's not in perfect condition, there is some pitting to the plate though not a lot of scratching or wear. It's 10" across the bowl opening, the flange to hold the bowl is a little larger.
