This is an amazing example of a pure beaver hat made by the John B Stetson Co. from the 1920's. It's in amazing shape considering its age. A few tiny moth spots that could be sanded out during restoration if you choose to take that route.
It obviously lacks a sweatband and silk liner, which a good hatter could install for roughly a $100. I haven't done that because the person that buys it has a little leeway when it comes to sizing.
All original, inside diameter is roughly 21.75 / 22 which is roughly a size 7.
Brim measures 5" with a pencil roll, crown measures roughly 7".
Braided raw hide hatband is not original, but I'll include with the hat.
