Thanks Gaspare- good to see you as well, been too long!
Next contention is- "the engraving was done on a round ring hence the angled cuts"
Here's a relatively small badge from the same period. Also features the same angle cuts. How many people would believe the engraving was done post-assembly? Another physical impossibility. It had to be done with both parts separated. And if both arts were separate then why angle the chisel?
The chisel was angled because it's one of the hand engraving techniques. You run the chisel straight and it will not eliminate any material other than mark or score it- it is not a machine engraver or roto-tool after all.
