Knutsen Convertible Harp Hawaiian Guitar

Here's more evidence that these particular style guitars were geared toward the Hawaiian players: this one has only inlaid flush frets - so the convertible neck really has no useful function.
This one has a slightly different variation on the point - a slight carved bevel on the back.
The two rows of photos illustrate the problem of trying to determine (and present) the true color of these instruments. Most likely, the color lies somewhere in between.
