The Duesenberg Les Trem II in chrome finish. It is mounted in place of a stop tailpiece. No drilling, no routing, simply screw into the two existing threaded bushings with the enclosed bolts. With round lever for optimum handling! Incl. metric and US screws. Important: The distance between the tailpiece bolts must be exactly 81.5 mm (measured from centre to centre). Otherwise the Les Trem won't fit!
