Headgear Ottoman janissary 1810-1826 ?

[Shipka]

During the back end of the Napoleonic era and into the opening engagements if The Greek War of Independence the typical high headgear worn  by the janissary corps was replaced by a quilted hat,
whilst there are a few pics of this hat there are no detailed pics of the top, can anyone help?

I'd hazard a guess that the quilting tapers into the middle of the top........ Fixed with a button?

[Shipka]

I had the same thought

[joroas]

The picture in the middle suggests some kind of black button or pom pom.
