I sure did not mean to offend you Bob. Quite the contrary,I admire your work. But the rifle I described does exist. No doubt about the rifle being made in the 1800's and someone, in the 1970's replaced the lock with a new one. That lock has the word ROLLER on it. I have seen quite a few of your locks but the name was always on the inside. Did you ever put your name on the outside of a lock ? Please forgive me if I offended you about inferring you were around in the 1880's. I am at my worst when I attempt humor. Johnny Walker
