Heh, just saw this post, bringing it back from the depths!
I met Mr. Offenberger at a Ohio Longrifle Collectors Assc. meeting in October.
He is alive, still building guns, and very fine guns at that! I'm not one for all the inlays and such, but they are beautiful.
He was very friendly and I talked to him for about an hour. I asked all sorts of questions, and he answered them all without hesitation.
