This is a very nice addition to any Southern Railway collection as it is so often near to impossible to find cups and saucers together, especially the harder-to-find demi sets.
The saucer is made by Sterling and is 4 7/8” in diameter with minimal use marks.
The demi cup is also in excellent condition with only light use marks and a couple of minor glaze pops. But it does have a deep, dark gouge from manufacturing on one side that is about a quarter-inch long. This is shown in the photos.
