Thank you for your help ! Where is this information so i could maybe buy the book or something for the future?
Thank you again

The numbers all are in the RZM Handbuch and the issued through time!

Hi Zacker,
we think this is the case, not easy to have this certainty with a black and white photo.

IMO does not look white at all compared to white on diamond & eagle.
