Identify possible Kona I recently found this bike at a thrift store and although it looks pretty haggard I'm thinking it is a Kona. Some help identifying the model and such would be appreciated.

Serial number is F712K1083 and nearby are the numbers 81-30 as well. I have no way of knowing what parts are original but on the side of the seat there is a K
I looked around online already and it seems similar to the Kona Kahuna but I'm no expert.

I gathered from some things I read that the serial number can be read as: F=Fairly Factory/7=1997/12=December but that's as far as I got. If that is correct, does the K stand for the model?

Thanks!
The K logo is definitely not Kona, my daily rider is a Kona Fire Mountain. KonIA (Konia) maybe? Lower end MTB manufacturer.

BTW my saddle and seat pole definitely NOT Kona. I broke and replaced them myself!
