The concept of the restoration: The investor wanted to bring the instrument into playable condition. Therefore, after initial research and consultation, restoration of the instrument started. The instrument has been sensitively restored and brought into playable condition (it can also be used for concert playing) while maintaining its integrity and authenticity – as many original parts as possible have been preserved, leaving patina and traces of use and subsequent modifications. The instrument does not bear the signs of contemporary intervention – restoration, and gives the impression that it has been preserved in this condition and form.
