vintage silver plate roast meat or turkey platter, tree & well for drippings

Beautiful old unmarked silver plate serving platter with tree and well design for catching juices and drippings from roasts or game. We believe this is probably silver over copper or brass, American made, mid-century vintage. 

This measures about 18" x 14" across the rim, big enough for a turkey! It's tarnished, but the plate looks good, we'd expect this will clean up nicely with a good polishing.
