C3017 Holzapfel & Beitel 12-string Mandola ...Circa 1905. Bowl-back or Neapolitan style mandola with a 9 3/8" top width and 16" scale length. Spruce top, alternating curly maple and rosewood back ribs. The original inlaid pickguard has been extended (most likely by Holzapfel himself). During the late 19th and early 20 centuries, triple course mandolins and mandolas, sometimes called mandriolas, enjoyed a brief popularity. Even today there are some musicians who prefer these instruments to a regular mandolin because of the fuller sound the extra strings provide and because tremolo is easier on a mandriola than on a standard 8-string mandolin or mandola. No case. $600.00
