(At $45 new, it was fancier than the $32.50 Duolian,
but still very common. And the maple neck doesn't sound as good as the mahogany neck Duolian.
Single cone resonator with a steel body and maple neck. A basic National
single cone resonator guitar model.
A good sounding guitar, just not very fancy.
I especially like the 1929 to 1935 metal body Triolians with
the Polychrome finish and the black stenciled Hawaiian scene on the back.
I would really like to find a 1934 National Triolian in Polychrome
with 14 frets clear of the body!
