Yep, the original. American made Klusons from before when well, you know. As used on innumerable Martins, Gibsons, and any other guitar company that would spend the money for them. Solid aluminum rollers, nickel-plated with nickel-plated gear screws. Taken from a Gibson classic guitar that got wrecked at least forty years ago and been untouched since. Could use a little cleaning but about as tight as the day they were made. Comes with all eight original mounting screws. $149
