Three Pieces Vintage Semi-porcelain

W. H. Grindley England 3 pieces of 1906;semi-porcelain, They are gorgeous!, soap dish, drinking cup, toothbrush holder. All are marked. I believe it to be a wash basin set. I thought the soap dish was a powder holder Used to hold soap and prevent it from becoming soggy. Can be cleaned with a solution of water and white vinegar. and it does show usage with age. Toothbrush holder and cup are in excellent condition. no chips or cream packs on any piece.
