In response to Deuce50's question about what I used as a finish on the barrel and lock, it was Kibler's Patina Solution. I carded it back to the level that I liked. I don't know how well it will hold up or whether it will give too much glare from the sun when shooting. If it does, I might put on another layer(s) or go back to rust browning, which "got away" on me the first time I tried it and resulted in an unacceptable "pebbly finish".
