Australian Bush Hat, that's what it says on the label
This hat is made of leather with a wide brim to protect the wearer from the sun and rain.
The leather is a bit mouldy but will easily polish out, whoever owned it last must have put it away damp.
Around the crown is plaited leather band, its got a cowboy hat feeling and is probably a style used by Australian cattle ranchers.
The crown is creased telescope style from the way its made
Like most bush hats it's vented in the side
