This vintage hat was made by Peters Bros Inc of Fort Worth, Texas. It is the Texas Hat, the Shady Oak Bankers Special One Hundred. Costing $100 new in the 1950s, this was an incredibly fine high end hat, made from Swiss felt. It was made for a Max Krauss. Please remember that the X rating system has inflated grossly over the years and that it has no consistency from manufacturer to manufacturer, so the 6X rating on this made it, at the time, one of the finest hats money could buy. It is a 6-7/8.
