banzi,

That Kreighoff built Kettner is a good buy. I sold a very nice Kettner to Lee LeBas a while back. It was a best quality side plated 16/16/8X57JRS that weighed 6 1/4 pounds. He is now advertising it for 2 1/2 times what he paid me.

Kettner marketed only the finest maker's guns.

I'll take some pics of the 12ga next to the 16ga; the difference is marked. This configuration is by far my favorite, as it doesn't use the Greener side safety, but a top tang safety, and one can cock/un-cock the rifle.
