This vintage hat was made in the late 1950s by the John B. Stetson company. It was sold by Wagner’s in Bozeman, Montana, has a bound brim and a two cord hatband. It is a size 7-1/4.

The big difference between a boss of the plains and a campaign hat is the grommets. An army campaign hat has them. A boss of the plains does not. Typically a boss of the plains stays uncreased, while a campaign hat gets a four point montana peak. This is a boss of the plains that has been adapted for NPS service.
This is a BIG hat. Tall crown. Wide brim. Likely made in the 1920s, it was sold by Moore’s of Santa Fe New Mexico and is Stetson’s No. 1 Quality, one of their western designations of the time.
