Vintage Gibson ABR-1 bridge, slightly used. Was on an ES-175 for a time. Comes with original wood bridge and paperwork. Delicate wire intact with flat thumbwheels. Prior owner scribbles notes on paperwork and box interior. Conflicting information. Box is from the late 50's and says nickel; however the bridge appears to be chrome plated, which would date it to the early 60's. Price reflects this conflict. Welcome to reasonable offers.
