I have a full set of china 136 pieces marked Royal Ivory, KPM crown mark A.D.1831 and then stamped Oakland China Glass Studio. Normandie Pattern. I can not find this anywhere. It has a 24 kt gold rim. Can anyone point me in the right direction to find out the value of these. Thank you in advance for your time.:) [img size=160]https://kovels.com/media/kunena/attachments/legacy/images/china.jpg[/img]
