I know the range you mean, the stippling is different with "veiled" raised shapes beneath the stippling. But as you say Stolzle did use stippling.
I was pronouncing "Schale" as in "school" and coming-up with "scale". The decoration on the "Schale" bowl in the 1937(?) catalogue seemed similar from memory, but is completely different on closer inspection. Sort of a cross between scales and a Celtic Knot design.
Thanks for your help and suggestions.
