Adjustment screw for German Pusch-style tailpieces. Sold per piece.
If you need the small tailpiece insert nut, let us know. Otherwise shipped without (the nut rarely needs replacing but we have a few in stock).
The mechanical part of the Pusch tailpiece consists of the fret wire, lever, and screw, and nut insert.
Compatible with Wittner cello tailpieces, but the head is a bit different style.
