Two old hand formed "Boss of the Plains" style hats. Feedback Welcome.

[sunnynature22]

Today I found two old, handmade, hand-formed hats. I think the style is called Stetson "Boss of the Plains" but there are no labels. They have a gaucho cowboy "feel". I'm guessing they were probably from the 1800s. They are stiff. I found them in the same recycling spot where I found some very old Apache Indian baskets a few months ago.
I'm not sure what material they are made of but they seem to have fibers.
Any guesses, comments or feedback? Thx
