vintage England Wedgwood Edme fluted pattern plain cream china luncheon plates brown stamp

Lot of three vintage Wedgwood Edme luncheon plates 9" in diameter. These are made in England, brown backstamp as shown. Not sure of the exact vintage on this marking.

There's no scratching or utensil marks on any of these pieces, no chips or cracks, but they do have a few brown spots from foxing.
