It has the makers mark of a spider web with a 5 pointed star in the center and a w in the center of that. It also has the word quadruple plate .At the bottom of the star in big numbers it says 128.
This is a washstand set that was at the home of my Great Aunt in southern West Virginia. She was 90 or so when she passed away this year. As the area was a coal mining area and our family worked for the coal company, I am thinking it was purchased at a company store. I tried to include a photo of the stamp on the bottom of the pieces. I am curious to know what the large lidded pot was (is) as well as the smaller one with the round insert. Thinking the latter is maybe a soap dish and the former something for the used water.
