Featured Help identify mark on Venus after the bath figure

I cannot find this mark that is on this white bisque figure of Venus after the bath. There are also two impressed numbers along the edge. I remember when I bought it, the person said they thought it was German. She is about 12" tall.

 

I believe white marble-like bisque is called Parian Ware. She is beautiful.

 

Don't have the book in front of me, but I'm reasonably sure that mark is in Rontgen. Sitzendorf?

I have often confused that mark with Sitzendorf.
