I see no makers mark on this sweet tureen. The number 250 is incised in the clay. It is a slightly creamy white and the ladle is a bit "whiter", most likely purchased separately by the original owner. It is NOT ironstone but rather regular china or porcelain. Free of chips or nicks. There is an under glaze smudge on lid and a few glaze pops, all shown in the last 2 photos. Very minor, production issues. It measures handle to handle 14", 8.50" tall. Feel free to ask questions and as always we are happy to combine shipping to save you money!
