Hi
The officer helmets do not wear two identical Kokarden
The officer helmets do have stars insteed of nuts and screws at the base of the spike
The rosette, fixing the chinscale are for officer. It should be steel screws and nuts.
For me, this helmet is mixing pieces which should not be mixed. And no explanation to be found with any war stories.
Furthermore, I do not see a Dragoon helmet, which has square leather visor.
All in all, if you happy with your helmet, everything goes well.
