KK 12 gauge

[bigcreekmetal]

Well I came across a single shot 12 gauge stamped KK on its side. No other markings besides a serial number. Its a neat old gun that breaks down into 3 piecs. From what Ive read its a hardware store type but any ideas what its worth? Is it worth $100 in good condition?
Thanks,
Josh

I've always thought there is something neat about single shot shotguns. Probably because I started out with a single 4-10. In my view, if it's in good shape and it's safe, darn straight it's worth $100.00.
