Ko'olou KS10

Have an opportunity to pick up a nice Ko'olau KS10 but cannot find much information regarding this model. Can anyone shed any light on this model?
Thanks in advance!

I'd think the letters indicate that it is Koa wood and Soprano size, probably one of their simpler (less adorned) models; I think they stopped making this type of more affordable models in about 2012. Great score, congratulations!
