This listing is for the 2 dozen (24 pieces) Aubert made in France 4/4 violin bridges which are shown in the photos. These bridges are out of my private stock. They are treated new and unfitted old stock. They were manufactured circa 2002. These beautiful bridges are guaranteed authentic. These bridges require a professional to custom fit them to each violin. These bridges cannot be used on any violin without proper fitting. If you are not a professional violin maker or a violin repair person, do not attempt to fit these bridges to any violin. You will receive exactly the same 2 dozen high quality bridges as shown in the photos.
