Here's a 99% original, one-owner, square-neck Style 1 Tricone. Its all original except for a replaced "lower nut". The original owner put that new nut on there so you could play "regular guitar" on it... well regular...

1929 National Style O. Originally a squareneck that was converted by master luthier Larry Brown to a traditional round neck. Plays like a dream and sounds exactly like a 1929 Style O should. Comes w/ non-original gig...
