Being a collector of Indy fedoras, I'm in the midst of getting ready to order a Indiana Miller #256 hat. I have been looking over the brim sizes, but I don't know which one is more closer to the brim size in Last Crusade. The Brim Sizes are 2/34",2 5/8", and 2 1/2". I was wondering if anyone which of these sizes most is like the Last Crusade Fedora brim. I thank you for any information any of you can give.
