Oahu and Bronson are closely related, started by half brothers (Oahu) who later split up into the two companies. Their guitars were Chicago made, by Regal, Stromberg-Voisinet or the Kay Custom Shop (in which the top end guitars were made by old world immigrants who had made guitars in Europe).
An Oahu of this quality is extremely rare; most were student grade or ladder braced. Most were made as lap-style guitars for the Hawaiian music craze in those days. This one is a maple Nick Lucas style, 14 1/2" bottom bout, 4 5/8" deep, scale length 25 5/8", with an Abalone border, natural top and sunburst back & sides. Originally a square neck and beautifully converted with a forgery grade neck shaping and sunbursting. These single X-braced boxes tend to be some of the best sounding flat tops. This one is woody and dry yet with the kind of sustain that allows its balanced voice to soar in every register.
