Shape is exactly same as hats for officier de grenadier de la garde impériale described in best specialized books (see last picture from must have book: "Margerand: "Les coiffures de l'armé française").
Felt have the obvious aspect of a 200 years old felt, some details of confection sign a production of the beginning of XIX th century.
Condition is good, only leather is absent.
Button is OK, same for bullions. Till now, everything is OK.
But cockade is probably made from a white cockade of restoration period.
Usually theads used to make cockades durins Empire were blue, red and silver.
Here, back is white, and front has been (well) paintedin 3 colours.
Was it done during 100 jours or just modified for collection by someone who could not find this rare eand expesnsive type of hat?
As we don't know, we sell this nice hat at less than the quarter of a pure original hat certified 100 % 1st Empire.
