- Zither: Lehner, Franz in Munich, Germany (1867). V&A Search the Collections. V&A Images. "The Alpine zither was developed by Johan Petzmayer (1803 - 1884) in Munich during the 1820s. The musician would set it on a table and press the five highest strings down onto a fretted finger board with his left hand, and pluck them with the thumb and index finger of his right hand, strumming the other bass strings with his middle and ring finger as required.", "This example was made by Franz Lehner (1801 - 1878), a violin maker who spent most of his life in Prague, but was based in Munich in the course of the 1860s. This instrument was displayed at the Paris exhibition of 1867 and bought by this museum shortly afterwards.";
based on Baines, Anthony Catalogue of Musical Instruments in the Victoria & Albert Museum - Part II: Non-keyboard instruments by Anthony Baines, London: V&A Images, pp. 72-73 “"A normal 'Salzburg-form' zither of its period. ... The fingerboard has twenty-nine frets and is traversed by five strings (two steel, one broass, two overspun) tund by four machines and one wrest pin. The twenty-seven overspun accompanying strings are tuned by wrest pins.”
- Martin Zither. Zither US (zither.us). "This zither photo was sent to us by Dick Boak of the Martin Guitar Company. The concert zither, shown below, was made by C.F. Martin, Jr., circa 1882 and is currently on display in the Martin Museum.", "Martin Zither (ca. 1880-1882) - Upon request, C. F. Martin, Jr. made a few zithers for Professor Louis Brachet, of Philadelphia. These were nearly identical to their European counterparts and followed the Salzburg form. The five strings over the short fretboard distinguish this as a “concert zither” as opposed to plainer models."
