Another grill topic from me...
I came across what I believe to be two copies of sc 89. I count both at 14 by 16 (and some) points. Vertical ridges. I would say both have quite well-aligned grills at right angles.
What puzzles me is that the two potentially identical stamps appears quite different.
Stamp 1 below has a grill which is highly visible from the front. On stamp 2 I can hardly see the grill from the front at all.
Is this due to 'normal' difference in the pressure applied when 'embossing' the grill - or is one - or both - fakes?

Any help appreciated!
