In post # 357479 C. Wetzel introduced the 'Deutscher Brummer' pattern with a quite modern script of GEBR. MÜLLER STUTTGART as distributer's mark.

By chance I sicovered in my files two illustrations from corresponding with a German collector friend in 2016.
Please not the different more vintage script of GEBR. MÜLLER STUTTGART.
