I have one of Ken's Rifles and I plan on keeping it in my collection as long as I have a collection. It is a .40 cal with a swamped 46" barrel and Chambers Golden Age Lock. It is long, slim and IMHO is the epitome of a golden age rifle. Fit and finish is excellent, wood to metal inletting is perfect. I don't believe you would ever regret buying one of his guns.
I am attaching a few pics I just this afternoon snapped with my phone so please forgive the poor quality.
I've been to Mr. Nettings shop on several occasions, he helped me out an awful lot on my first build. I've watched him in action....and I'll tell you this, Ken Netting one of finest craftsman I've ever seen in action.
I'll be at his shop in a couple of weeks... I'll ask him. Ken has been gracious enough in the past to mentor me on a few projects here and there. God willing he will be there to help me through quite a few more...I get myself into some messes for sure.
Well I visited with Ken this morning, he helped me straighten out a fowler I purchased from another fella. I purchased one of his brass primers that he makes...I wish I could figure out how to post pics on here.
Anyhow, Billiinoregon,to answer your question, Ken did not mentor Roy Stroh. Ken says he knows him but didn't mentor him.
