I have a 125-150 year old Chamber set that I am trying to identify and value. It is white with gilt pattern, and gold bands. It has the mark "Lois" on the back, in blue with a circle around it, and also the #1711 gilted on the back (possibly a pattern #?). The set includes the big pitcher and bowl, a smaller pitcher, a comb holder (we think) and a soap holder with lid. No thunder mug or chamber pot. If you can help me with this identification, I'd apprecitate it!
