vintage silver / sheffield plate meat platters, tree and well for drippings

Three vintage silver plate serving trays with tree and well for catching juices and drippings from roasts or game. We believe all are probably silver over copper or brass, good old sheffield plate. All are American 20th century I think?

The largest platter is very heavy, and measures 18 1/2" across the rim. The two smaller platters are lighter in weight, a little under and a little over 16" in length. The smallest platter has a slight bend to the rim.

All three pieces have tarnish, so it's difficult to make out the markings, if any. The plate looks good on all, we'd expect these will clean up beautifully with a good polishing.
