The rollers are labelled: Koppers Feuerland, but they were presumably taken by Gusinde (letter from Gusinde to Schneider dated 2 March 1938), whereas according to Koppers (letter from Koppers to Reinhard dated 8 January 53) they were taken by both together. Koppers published a book about his experiences before Gusinde and independently of him (Koppers 1924), but there is no reference to the roller recordings in it. The original document is missing, the contents of the rollers can be seen in the EB Schneider. There is no correspondence concerning this collection. Transcriptions of some rolls in Hornbostel 1936. A copy of rolls deposited in the Museo Historico in Santiago de Chile was made in 1971 (cf. correspondence Christensen/Dannemann). contents: traditional chants and voice recordings.
