Thank you so very much for the alert and for pointing to my own items!
- Another incorrect attribution on my pages!
I had completely forgotten about that one and it is nice to get corrected finally, now that we know who the maker is! This bowl belongs to my collection for decades, hence the quite early, low number 00813.
The pattern is so similar to Radeberg's 1927 resp. Walther's 1933 MERKUR that in the late 1990ies I 'decided' this must be Walther as well
I enclose the old images for all to see - and another photo comparing Radeberg/Walther white MERKUR to rectangular pink 'FAIT EN BELGIQUE'
Thank you again!
