Hi, hoping someone can shed some light on a purchase I made yesterday. It is a “personal wash set”, 4 pieces consisting of a chamber pot, a pitcher, and two other smaller pieces. On the bottom they are marked “Admiral V.P. Co.” I’ve searched various sites online, and cannot find any information on the company or on the item. It’s a pretty floral pattern, purple flowers on a white background, and is in very good shape. The seller thought the piece was made in the 1800’s, but I cannot verify it nor even start to guess at it’s value. Help!
