Item L6d in the catalog of Czeslaw Miłczak, who classifies this variety as a forgery.
The print is on paper without watermarks, analogous to variety c) the differences are similar hatching in the "No" and differences in the size of the numerator font, especially visible on the larger and bulkier digit 7, an additional characteristic is a trace of numerator ink between the No and the numerator string, as often seen with this variety with the so-called "jumping numerator" feature. - here on this piece the last digit of 7 has clearly fallen off.
The issue of the designation of this variety as a forgery in Miłczak's catalog is controversial and still debated. Grading in PMG does not classify this variety as a forgery.
