Kamaka Pineapple Ukulele *Vintage* with Case. Gold Decal & Double K

Description

Very good condition given its age.  Includes a soft case with snaps.  I believe this is a soprano.
It has a gold decal in the interior and a double-K on the headstock.
The KamakaHawaii,com
website states:
"
This combination of decal and label was used until 1969."
Online they say the date the instrument was made is stamped inside, but I cannot see a date.
To the best of my recollection my mother brought this ukulele back from Hawaiii in the late '50s.
There is a slight rise on the bottom but I see no separation and I believe it was made that way; see photo.
I do not know if the case was
purchased with the ukulele; the case is felt-lined with a tight fit. There are no tags on the case.
It sounds nice when strummed but I never learned how to play.
