Das historische Instrument besitzt keinen Zettel und bewahrt seinen originalen Schellack.  Das Cello wurde von einem Instrumentenbaumeister aufgearbeitet, \u00fcberholt und spielfertig gemacht. Damit verbindet es den individuellen Charakter eines \u00e4lteren, gespielten Instruments mit einer fachm\u00e4nnischen \u00dcberarbeitung f\u00fcr den weiteren musikalischen Einsatz.  Ausgestattet ist das Instrument mit Larsen-Magnacore-Saiten. Als historisches Cello ohne Herstellerzuschreibung steht bei diesem Einzelinstrument vor allem die erhaltene alte deutsche Arbeit und seine fachgerechte Aufarbeitung im Mittelpunkt.",
