I think I have the same bell: however, my bell has C.W.R. for Captain C.W. Rogers. It is a miniature reproduction of the original bell cast in 1880 and is called the Captain C.W. Rogers Centennial Brass Railroad Bell. I found this information on the Internet. On the Internet, it came up under the heading Frisco Railroad. The web site is http://www.frisco.freewebsapce.com/Misc.htm

This information was from a couple of years ago, so the web site my not be active now.
