National Duolian Resonator Guitars

Description: National Duolian Resonator Guitars
Available: 1930 to 1938.
Collectibility Rating: Squareneck: D-, Roundneck: C (a great sounding single cone National, but they made TONS of them since they were only $32.50 brand new).
General Comments: Single cone resonator with a steel body and wood neck. National's basic and least expensive resonator guitar model at the time. A great sounding guitar, just not very fancy.
