I bought a white wall plate at a thrift store. On the front, in blue letters, are all the Meissen marks from the “AR” monogram to 1934. The last mark is blue crossed swords with “0072” 1934 “ab” written underneath them. On the back is the blue under glaze crossed swords in the middle of the plate. In the far upper right is a very small “72”. On the lower right is a very small stamped “N 11” As it says above I have exhausted every resource I have access to and cannot find it.
