There number is limited within Tielke's oeuvre: there is one complete instrument (in the Victoria and Albert Museum), one body, and the fragment of a neck with its pegbox. Of special interest is the questions of their previous owners.
The disposition of the complete though alterd instrument shows six bowed and 22 plucked strings, however, the fragment has only nine plucked stirngs. This makes one assume that the fragment might be earlier than the complete instrument, yet setting the less complictaed before the more complicated is too easy an assumption as examples from other types of isntruments show. They are often co-existing according to the needs and wishes of the indiviual player.
