This is a single length gut core string with sterling silver and copper wires wound on to the gut in tandem, with a thin silk layer wound onto the core between the gut and wire. Because the wire is round, the surface of the wire is polished so that the string feels smooth. The end of the string that goes into the tailpiece is knotted and there is a loop of gut on the end. This knot will hold the string in most historical tailpieces, but may slip through a modern tailpiece. This combination of silver and copper wires is found on extant strings from the late 18th and early 19th centuries. The copper makes the string a little brighter in tone than a plain silver string.
