In point of fact, the issue Federal waist and NCO sword belts were just slightly less than the 1-7/8" width of the belt plate slots. Some of the Confederate belt plates have slightly smaller slots. Officers had to buy their own belts, and most were 1-5/8 - 1-3/4" slots widths. Two-inch belt loops sewn on holsters work fine with those belts! As to color, at the beginning of the War, most of the Confederate equipment was Federal pattern, i.e., dyed black! Later in the War, when losses of both men and equipment required new leather, the Confederacy and state fabricators used plain leather, sometimes dyed with walnut shells, etc., resulting in what we presently call "russet", which is technically "stuffed russet", or oil impregnated leather.
