Skłodka (f)
more or less "S"-shaped shortener, "reducing" the relative length of a drone; ➺Absolute/Relative length
From "składać" [to assemble] ?; According to Sobieska, a "set of drone pipes", which is a rather odd definition, considering that the instrument has only 1 drone; Observing its shape, however, it probably is the name of the "S"-shaped "shortener", instead (➺ Absolute / Relative length); One of its synonyms (Skręta) appears to support this idea.
Made of wood, the channels of the 2 pieces are connected with "U"-shaped metal tubes.
