Super rare Chicago-made (by Kay/Stromberg-Voisinette) Jumbo, basically a Nick Lucas body. Back and sides are maple, with the back most likely being laminated. Bracing is the more rare and higher quality X style. Also rare is the original round neck, beautifully shaped, instead of square, since Oahu was a publishing company selling Hawaiian slide guitar lessons. The extra-long scale means it will work beautifully with a bottleneck. The gold decorations are stencil/gold leaf with hand painted details, and beautifully done.
