Removed from a 2017 Les Paul Standard. This is the original Nashville-style bridge and tailpiece. They function without any problems and there are no issues. I think they are relatively clean. It's difficult to see, but they have the original API and ADVANCED PLATING markings from this period. According to the catalog, both are made of aluminum, so they are very lightweight. Please note that these are inch-spec, so those planning to install them on a guitar with metric specifications should be aware. Thank you.
