Index card (music eth.): A piece of skin is stretched as a membrane over a coconut cut on one side, the edges of which are folded over to the outside of the body and glued there. The body is pierced by a thin, square iron spike which widens towards its lower end to form a flattened foot. Above the upper exit point of the body, the round side support, which increases slightly in circumference towards its free end, is attached to the spike. Where a pegbox is recessed in the neck, two flank pegs penetrate the stick from both sides. The strings, of which only fragments remain, ran from here over the top of the body (a bridge has not survived) to the iron spike, to which they were attached near the copus wall and over a cloth wrapping. A thin, round and only slightly curved wooden stick, both ends of which are wrapped with a cord, serves as a bow stick. The horsehair stringing is clamped under the windings on one side. The stringing is torn and provisionally tied to the stick bow at the moment.
