I've searched through dozens of belts looking for a black fine leather, 1 1/4 inch wide with a rivet to hold the belt loop. Well, this was the closest I could find, but it's 1 3/8 inches wide (making it a little tight in the belt loop for some). It also doesn't have a rivet, but it has enough extra skin for me to attach a "Chicago Rivet". I don't care about the metallurgy of the buckle, but it matters to some.
