This vintage hat was made in the 1950s by Peters Brothers Inc. of Fort Worth, Texas. It is “The Texas Hat” – the Shady Oaks Banker’s Special. Later models would change the name to the Shady Oak, dropping the s. These were the models famously presented to presidents, and worn by wealthy Texas oilmen. It retailed for $50 in the 1950s, an extremely expensive hat for the time, and the quality really shows. I would say it is comparable to Stetson’s 7X Clear Beaver felt of the period.
The beaver felt hoods used in these earlier models were made in Switzerland. I have read they used these imported felt bodies because mercury processing was still done in Switzerland at that time, which resulted in a higher quality felt.
