The Mark looks like the Schierholz.  However, I cannot be sure that it is.  Add a touch of elegance to your decor with this pair of Germany Porcelain Swans. The swans are intricately designed with 3D flowers and are perfect for all occasions. The figurines are made of high-quality porcelain material and are manufactured in Germany. The swans come in a set of two and are perfect for collectors or as a gift for someone special. The artwork style is Art Nouveau and the color of the swans is white. The swans are part of the MCM theme and are sure to add a unique touch to any room.
