You can look at my site for Kamaka info (it's in my signature below )
But a Gold label is between a 1954-1969, and during that time the headstock KK was a decal. So over time the KK on the one you've seen could have came off, worn off, etc. I've seen some where the KK is almost completely gone.
Aloha Trixie,
Do you have a picture you can post..if it has a gold label most likely it is one...could have been refinished at one time..
you know if you take it to kamaka and the say it is, they will put on a free new decal for you....
