This tarnished wire will fit any of the 1840 cavalry or artillery sword., It is the correct gauge and twist and has the right patina that will make your sword look good rather than adding bright stuff which is the wrong size. It also comes with instructions. If you need another size other than what is listed , let me know. I can supply copeper, brass, a in both coiled or twisted like shown here. I can supply them in 30 28 26 24 22 21 or 20 gauge in either brass or copper and twisted or coiled.
