This is a circa 1920 (give or take 5 years) Paul F Summers "Famous Waikiki Ukulele" in excellent all-original condition (No cracks/signs of major repair work) w/chipboard case. Most likely, this was made by ex Kamaka builder, Sam Chang, who built a lot of ukes for the Summers brothers (Paul & Harold) who sold them out of the Royal Hawaiian & Moana hotels. This is a fancy soprano model made of nicely figured koa with matching rope-style purfling and rosette. It is missing the inside label but has the "TABU" stamp on the back of the headstock that indicates that it was made in Hawaii between approximately 1915-1925 or so. Great sounding piece!
