One of the best ways to date your Kamaka (if the date stamp is gone) is by the label and headstock logo. Here are the different interior labels, and their dates.
I am missing some of them, and some of these are not that great or clear. If you have any better photos feel free to email them to me. Thanks!

1928-mid 30’s Pineapple Label
mid 30’s – ? Pineapple Label

(reads KAMAKA Genuine Hand-Made Ukuleles Since 1916 / Kamaka Ukulele Factory / Honolulu 19, Hawaii)
I’ve been trying to find out exactly when the first Concert size ukulele were made. By the font of this label, I would assume this Concert was made in the 1920’s. Also, it may not have been a regular model at this time, as they specifically mentioned that it was a “Special Concert Size”.
Gold Label 1954-1969
White Label 1969-2001
