hi,

looks like it's a bit high in the corner of the G string, as if it is about to pop out
(maybe it's just the pics, couls you post another pic of the bridge?)
I don't know that you can determine the exact year since they didn't serialize them. quote from the Kamaka website: "In 1969, the gold label was replaced by a smaller interior label with a white background and the same trademark red and black lettering. However, the same double K headstock decal remained in use. From 1978 to 2000, a "Samuel Kamaka, Luthier" label was also applied to the custom ukuleles.
