These pre-war electric instruments are fairly rare today, though the lap steels pop up with some regularity.
The archtop bodies for the guitars were sourced from Regal and then from Kay, but the electronics were developed and manufactured by National-Dobro.
This new top-of-the-line guitar was designed to compete with Gibsons Les Paul model, complete with a single-cutaway body and two large, chrome-covered pickups.
The solid maple body had ivory-colored binding and a matching plate covering the back.
About the beginning of the 1960s, Valco had ceased production of most archtop models and revamped its amplifier line.
National amps now bore flashy chrome panels, and the largest ones quickly grew to accommodate two 12 speakers, plus effects like tremolo and reverb.
Some models were available with Bigsby vibratos or Valcos own vibrato design, and the Silver-sound pickup was introduced.
These fairly expensive guitars came out of molds, not carving shops, and the result was unlike anything produced before or since.
