Hi all. some of you will know me from the GMB and other glass forums, but am a newbie here. I have been collecting some Fat Lava ceramics for a while now (and have the book!) but get stuck from time to time. Can you please help with the large one in the left. It has 553-52 W.GERMANY on the base., I think the other three on the right are Scheurich, but please correct me if I am wrong. TIA Emmi
