As it so happens, there is a letter with it from 2007. It was shipped in 1938 to W. A. L. Thompson Hardware Co., in Topeka, Kansas. It was shipped with a 5" barrel, blue finish, and checkered walnut grips.
When I take more pictures of the gun, I will also try to get a good picture of the letter. I will also pull the grips and check if there are any numbers on them.
So far, it has been to Kansas, Alabama, Ohio, and now Illinois. I wonder how many other owners there are?
