you see these chalkware items in lots of shapes and styles with numerous brand names. of 2 i picked up and looked at this morning ( dutch rural scene in relief) 'boello' ware stamped and impressed no's. the other is a jug, art deco style, fawn with geometric design (finish flaking off and very soft easily- damaged body as well , thats why i call it chalkware.. its like chalk) stamped  'rawleigh' with impressed numbers also.

thanks!
