Strange spike-helmet (at least for me )

[Robert Noss]

Found that photo today on a fleamarket. At home I looked closely to the spike-helmet and found it strange. Looks like there is a cockade or a hole in the middle of the eagle.

Maybe it is just a photographic irritation, strange from this angle, but I can not remember to have seen that type of helmet before.

and the detail of the helmet:

Any comments are welcome as always.

Sorry.
