Step back into the early golden age of resonator guitars with this 1932 National Duolian, serial C5968—a highly sought-after, rolled-F-hole version from one of the most iconic years in National’s production history.
This instrument is not only a standout survivor from the pre-war era, but also listed in Mark Makin’s authoritative reference book “Palm Trees, Señoritas… and Rocket Ships”, adding an extra layer of provenance and collectability.
 
National String Instrument Corporation, founded in the late 1920s by John Dopyera and George Beauchamp, revolutionized guitar design with its innovative resonator technology.
The Duolian—introduced in 1930—was National’s rugged, no-nonsense workhorse: a steel-bodied, single-cone resonator guitar known for its power, projection, and unmistakable blues voice.
 
By 1932, National refined the model into what many players and collectors consider the most desirable iteration. The rolled F-holes replaced earlier flat-cut openings, lending extra structural strength and a sleeker, more elegant look. These instruments became favored by blues musicians, street performers, and early slide players who relied on the Duolian’s cutting volume and soulful tone.
 
This 1932 Duolian is a textbook example of what makes the early-30s so coveted:
 
Authentic National steel body with original Duco finish character, showing the honest wear that only 90+ years of musical life can create.
Rolled F-holes, confirming its status as the sought-after ’32 version.
Original resonator tone: focused, gritty, and loud—with the unmistakable bark and metallic warmth National is famous for.
Listed in Mark Makin’s book, giving it provenance rarely found in vintage Nationals.
Comes with a 1960s hardcase, solid and road-worthy, offering proper protection for a guitar of this stature.
 
This is not just an instrument—it’s a piece of National’s history. The fact that it is listed in Mark Makin’s definitive catalog adds confidence for collectors and enthusiasts alike.
 
This Duolian delivers the classic pre-war resonator voice: punchy mids, cutting projection, and a haunting growl perfect for both fingerstyle blues and slide. Whether played in standard tuning or dropped down for bottleneck work, the guitar responds with authority and character.
 
Pre-war Nationals have become increasingly scarce, and the 1932 Duolian with rolled F-holes is one of the most desired production variants. Its combination of musical versatility, historical significance, and documented provenance makes this example especially collectible.
 
If you’re seeking a true vintage National—not just a resonator, but a historically important, fully authentic piece from the heart of the early blues era—this 1932 Duolian stands out from the crowd.
