The instrument made by A.E. Kram 1770 in Nuernberg is part of the Musikinstrumentensammlung Willisau / Switzerland.
The instrument too fragile to make it playable again. The aim of the restoration is to actively preserve the state of use. All loose parts should be fixed, missing parts added and cracks closed. The damaged rosette requires special attention during the restoration. Parts of the parchment mosaic are badly damaged and cannot be reused. The aim is to maintain and clean the parchment in three rosette windows. The rest is reproduced similar to the rosette of a cister in the Nuremberg National Museum. The cistern should be cleaned and strung with low tension strings to make the instrument organologically understandable. The probably not original bridge remains on the cister, comparisons with other cistern from Kram do not show a uniform bridge shape. The bridge is thus a sign of an authentic, changeable music practice that reacts to the needs of the musicians. The same applies to the later added wedge under the fingerboard, which should remain on the cister
