This vintage fedora was custom made in the 1960s from pure beaver felt, and originally sold for fifty dollars, making it extremely expensive at the time. I have owned many 7X clear beaver Stetsons from this era and the dress weight beaver felt has a very similar feel. It is a 7-1/4 and has a 2-3/8″ brim and a 5-1/4″ crown.
This vintage hat was made by Dobbs, as part of their Dobbs West line of cowboy hats. It is a beaver 50, which means that at the time of its manufacture, in the 1960s, it was a fifty dollar hat, making it extremely up-market. It is a size 7.
