Are You a Vintage Uke Expert?

How much do you know about vintage ukes? Are you a Kamaka expert? A uke reader sent in a question about a vintage uke he found at an estate sale–any information you can provide would be much appreciated by this fellow strummer.

Question: I purchased a Kamaka ukulele at a estate auction. Measures 20-1/4 in length. 6-5/8 at widest. It has is 6-3/4 to 12th fret. If anyone has info please advise.
