Firstly the font is not consistent as You send pictures about minimum 3 font of digits types, the die used by germans, same as by czechoslovak were not larger as 4mm, similar high digits about 5mm was not observed on any real pieces to this day.
We are talking about the SS and the rework being done in work camps. You can not compare SS rework number stamping to that done by Czech & or German. You have to compare SS Number stamping to SS Number stamping. The SS perhaps wanted their documentation to stand out from pre existing numbering and geometry.
