This is a set of Les Paul type bridge and tailpiece anchors. They were attached to a Burny Les Paul type guitar (made in Japan). This is from the era up to the mid-90s, when the truss rod cover had two screws. Both the bridge and tailpiece are marked "SG," but they were on a Les Paul type guitar, not an SG type guitar. Burny guitars have "Super Grade" written on the headstock, so it might be an abbreviation of that. They are old and show some signs of use, but I think they can be used without any problems. As a bonus, I'll include the strap pins that were also on the Burny guitar. Judging by the color of the screws, they may not be original. Please consider them as a bonus. #guitar #parts #bridge #tailpiece #LesPaul #Burny
