The 1886 carbine boot was a slight modification of the 1885 pattern that used a brass collar to keep the leather from catching on the rear carbine sight. The boot was designed to carry the weight of the carbine, and the carbine sling became more a way for the trooper to retain it if dropped from his grip in action.
This one is black leather in good condition with all straps and buckles in place. There is an inspector stamp on the end of the long strap but I don't see other markings. Finish is alligatored with crackling, but there is very little flaking. The dust was cleaned off and little dressing added, but the finish is not gummy and the boot still retains its open shape.
A good example of a regulation piece of Indian War cavalry gear.
