This 1920s Slingerland parlor was built as a Spanish-style guitar, but the neck has bowed considerably. Otherwise it's in great condition, and it has a loud, booming voice that belies its size. The price was right, too, so I turned it into a Hawaiian guitar with a nut extender:
Two Oahus that I used to own, a ca. 1940 Diana and a 1953 Iolana:

Some Valco Goodness - 1950s Oahu Tonemaster with the strings through pickup
Also a 1929-1931 First Hawaiin Conservatory of Music concert. You got this free when you ordered lessons from Oscar Schmidt's mail order music business. This was Schmidt's standard Stella - all birch, angled neck heel, square top kerfing, arched back - set up as a lap guitar. I converted it to a regular old geetar.
