Historic Compared to mandolins and banjos, manufacture of mandolin banjos grew scarce in the late 20th century. Historically, mass produced mandolin-banjos were made by companies including
Gibson,
Weymann & Son of Philadelphia,
Vega,
S.S. Stewart,
Lange, and the English company Windsor, who all built and sold 4 and 8 string banjos in the early 20th century.
Current manufacturers Today mandolins-banjos are being manufactured by Vintage, GoldTone, Rogue,
Cumbus, Morgan Monroe and Musikalia - Dr. Alfio Leone. GoldTone makes the
MB-850+ Mandolin-Banjo, with a removable maple resonator (converting the instrument to an open-backed instrument). The selection is not large and the instruments are not common in stores. Morgan Monroe has recently made three models, the MM-MB1 Mandolin Banjo the MM-MB2 Mandolin Banjo, and the Banjolin DLX (8 strings). The Morgan Monroe banjos look like traditional mandolin-banjos and have wooden resonators. The Cumbus model has a spun aluminum resonator. Prices currently range from around US$150 to $700. In Italy, Musikalia manufactures three models of Mandolin Banjo, always with wooden resonator (mahogany, padouk or maple root wood veneered), animal skin, but gives an alternative between simple or double aluminium ring. ==Instruction books==
