The owner of that mark was the Porzellanfabrik Kahla AG from the town of Kahla (Thuringia/Germany). The "PK Unity" marking was used for US export only between 1925 and 1932. The number may be the pattern. (I found this information on the "Artifacts Collectors" website) I hope this helps in searching for values.
