Previously owned Oiled leather Hat by Barmah of Australia. This is the 1060 Foldaway Bronco in  brown. (Might be rustic brown) Size large. It is still an active style and sells for $86 on their website. 

Size large HOWEVER, the interior of the crown is 22 1/2” and that is not large. To decide if this will fit you, measure around your head at the center of your forehead. If it is 22 1/2” or close to that it will fit. 

It has a wrinkle in the front as they are made to be smashed into a suitcase to travel. Clean with a little dust inside. No wear or body oils on the interior band.
