Just curious. Kamaka ukuleles had white and gold labels for various periods of time. I've been told that the gold labels correspond to ukuleles built in the 50s-60s and that the white labels correspond to ukuleles built in the late 60's through 2000. Does anyone know the difinitive answer? Do you know where I could find information like this on Kamaka ukuleles? Were there better years for Kamaka?
