I have an 1970's Herbert Johnson trilby in "Mix" Brown, size 6-3/4 or 54. The hat is 100% fur felt, is in great used condition and has some signs of wear. Some spots of discoloration on the sweatband. Sadly, way too small for me. Tag indicates hat was made sometime in the 1970's. Herbert Johnson is famously known for creating the iconic fedoras in the Indiana Jones films and some of the hats in the Dr Who series. Let me know if you have any questions.
