Yeah, he seems OK. I contacted him about your gun when it was for sale - in his ad, he said that the only problem was that the cylinder turned at full cock. I explained about the adjustment and he tried it - he said it worked great. He has some pretty cool guns for sale.
I went on a lever action gun forum when I got mine and there was a poster there who had three of them. I can't remember the forum.
Here's a link to a guy who sells some of the parts for the S&N (he knew nothing about the adjustment - in fact, he said I was wrong, there was no adjustment)
