This vintage hat was made by the John B. Stetson company in the 1960s. It is their Beaver One Hundred model, made from pure beaver felt, originally retailing for a hundred dollars. It has a lining from Rand’s of Billings, who probably did some cleaning or renovation at some point. It measures 21-1/2″ inside, about a 6-7/8″.
