Thank you for viewing. I received this as a gift, so I don't know the details, but I believe it's probably a Gibson. However, I'm not certain, so please judge from the photos. I believe it's a bridge from a 70s J200 or possibly a Heritage model. The material is probably rosewood, or possibly even Brazilian rosewood. If you have any questions, please comment. I will answer to the best of my ability. Type: Flat top Year of manufacture: 1970s Brand: Gibson
