Don,
I live about 35 miles from where his shop was, it was about 10 miles up the Snake river from Asotin Washington, Ron Reeser a local smith and I were going to buy some of his cryogenic treated barrels, when we got to his shop the tank for treating the barrels wasn't set up yet our next trip the doors were closed, that must have been eight years ago or so. I heard they were very good barrels but unfortunately never received one.
Wayne.
