My Country Tweed Hat got half inched, where can I get a good replacement?

Tweed old chap? one could replace such a decrepit old head piece with a flat 'ratter' hat of tan corduroy 'The Rutland' by Dunn & Co. is rather dashing and goes well with the Barbour jacket and green Wellies. I am surprised you did not fetch the perpetrators a sharp blow with your shooting stick.
