Johnah Kumalae was part of the second generation of ukulele makers starting in 1911. He quickly became one of the most prodigious ukulele makers around - making around 300 a month according to Jim Beloff's The Ukulele: A Visual History. This may account for the fact that, despite them being high quality ukuleles, they can usually be bought cheaper than most Hawaiian ukuleles of the same era.
