Boxer or Berdan??? How do I tell...See Pic

[Doc]

These are pics of some Hirt that I've got. How do you tell if it's boxer or berdan primed?

Them's boxer!
One hole in the case
The 'anvil' is in the primer.
Berdan would be two holes in the case,
no anvil insert in the primer.
There would be a nub in the case to act
as the anvil. (between the holes.)
(anyone got a good picture of the inside of a berdan round?

Good pictures, btw.
