It is Water Buffalo.Thurston Bros has a buffalo Thedi with buttons that I've been eyeing. The fit would be darn near perfect. Buffalo leather has never been my bag. Always seems flimsy and costly for little reason. However by looking id never guess it was buffalo. Maybe they're different in Italy. Id kill for a 10% off code lol. I can dream
You are probably thinking of American Bison. A completely different critter.
