Additional Marks on Eschenbach set

[aringer]

I recently purchased a creamer, sugar bowl, and coffee/tea pot (still haven't figured out which), and I'm trying to identify it.  So far, I've been able to learn that the pattern is #7388 (according to replacements, ltd), and porcelainmakersandmore.com places the mark between 1945 and 1949.  However, the bottom of the mark also includes the words "La Reine" and "Weiss".  There is also a set of numbers below that which appears to be embossed.  The numbers are the same on all three pieces. 
Does anyone have any idea what these additional marks mean?  Thanks in advance for your help.
