Knutsen Seattle Harp Guitar HGS5

This instrument is pictured on p. 68-69 in the Noe/Most book. The images below are from the original seller, The Red Fiddle.
Note the new shape of the bass headstock.
You can see that it had seven tuners on the neck, with a hole for an eighth. The image on the right, from the book, shows the new separate eighth tuner that Dan Most re-installed. The strings are configured so that the "g" and "e" strings are doubled! As there is another instrument (HGS25) with the g string doubled, and because the eighth single tuner sticking out of the top seems too wacky even for Knutsen, I suspect that he or someone else added this later. But with Knutsen, it's certainly possible that it's original!
The binding and ornaments are quite fancy on this one.
Based on the proportions, it appears to be a 3/4 size instrument (~19" scale length).
Additional photos and information can be found in From Harp Guitars to the New Hawaiian Family by Noe & Most.
