I bought this as my first ukulele (pics here), thought it would be neat to have an older one as my first. It was from the estate of a gentleman who collected high end instruments. I was told he bought it "decades ago", maybe in Hawaii, and that it was handmade and that he considered it to be of very good quality. Unfortunately, there is no markings or labels aside from a mark embossed into the wood inside that says "Made in USA", and remnants of glue where there would normally be a label. There is also engraved into the headstock by hand the initials "R.D.R." but aside from that I am at a loss! Please help me learn more about this ukulele!
