Here is a 14-fret vintage Duolian. I still has its green frosted duco finish with a very slight burst. The neck has been refinished, but the guitar still has the original cone, tailpiece, and tuners. The slothead style headstock on the 14-fret necks were only around for about one year. In 1935 the headstocks were changed to a solid style. Like the 12-fret style guitars they replaced, the very early 14-fret Duolians had mahogany necks with the stamped “National Duolian” on the headstock. That soon switched to basswood and a Duolian shield style decal. This guitar has a basswood neck.
