this confirms the Flumann connection to Kreuzwertheim, Bavaria.
As I posted before there was the so called Flumann Halle, used by company Kümmerling after WW2. It was removed for a kinder garden.
Flumann had cooperation with company Stuhl Hofmann (furniture company, chairs), just beside the Flumann Halle, Hofmann also producing for Flumann.
Flumann, Erla, makes sense
By the way, see
