In 1964 Rock Wood Carvers of Oregon, Illinois formed a subsidiary company “The Steam Instrument Co”. for the purpose of making banjos. Later the name of the company was changed to the Salstrom Banjo Company.
The instruments produced included banjos, tenor-banjos, plectrum-banjos, and the long necked folk banjos. Prices ranged from $122 to $245.
Do you have a pre 1940's banjo by this maker? can you supply us some images?
