Peach colored mugs have a "W" marking on the bottom

Bought two manufactured looking, creamy glazed peach, pottery mugs today. They have a W marking on the bottom. They match in every way, shape, size, color and glaze, except the handles are different. One has a pointed/ angled grip and the other a "two fingered" grip design.
Does anyone know something about them or their manufacturer?
