I have an Aloha Royal minus the binding looks just like this one. I asked the vintage ukulele web site for information and this is what he wrote, “Aloha Royals were made by the Tokyo Stringed Instrument Co who Kamaka (the big Hawaiian maker still going today and making some of the best ukulele s available) got to make the Mahogany Keiki Kamakas because they were that good. (Kamaka may have actually owned the Tokyo Stringed Instrument co? I’m not sure) What you have is an example of the absolute top Japanese Ukulele maker of the period and worth a minimum of $200 probably (and definitely ought to be) worth more “
