Phenomenal! Any idea who the maker might be? I have one with the same paper labelNot strictly a bowler, but I wouldn't know what else to call it. It was part of the two hat deal and it was the one that caught my eye. In style it resembles as Cambridge bowler, but to keep it French let's call it a Melon Sorbonne (which isn't a thing, but has a nice ring to it).
Mouroux & Cauzeret chapeau melon. Size 55 with the brim at 5cm and the crown at 13cm. Corded and with a clasped bow set halfway between a side bow and a backbow. Two gromets on either side and a cord of unknown function. I think this a very early style and the hat certainly shows its age with the felt won down to the shellac on most of the brim and either mothing or wear has done a number on the front of the crown as well. Can't wear it but I still like it.
