The Lone Ranger's last name, Reid, was disclosed in "A Look To The Future", January 4, 1950. Only his last name was mentioned, as he says. It's possible that a 1966 book titled, "Radio's Golden Age - The Big Broadcast", co-authored by Buxton and Owens was the source of the information the name was John Reid. The writers inserted it into the 1980 Lone Ranger film but it was never part of the original canon.
