From Wikipedia
The eleven-string alto guitar (also known as altgitarr, archguitar, or Bolin guitar) is an extended-range classical guitar developed by Swedish luthier Georg Bolin in the 1960s.
Original Bolin instruments are now rare and valuable. The Bolin alto guitar most often has eleven strings, but Bolin also made a thirteen-string version.
