Locomotive bell identification

[drygirl04]

I need some help me identifying a bell that I inherited. I am confident that it is a locomotive bell. My uncle worked for the Missouri Pacific Railroad. He worked as a clerk at the old engine facility in downtown St. Louis. If memory serves, this was taken off of a switcher type diesel locomotive. I was given this when I was a kid. I am looking to restore it. When I was younger, I stripped the paint (MoPac Jenks Blue) and left the brass/bronze material exposed while painting the inside of the bell and ringer red. I know that was probably a mistake. I am confident that it is not an EMD bell because of its shape and it is unmarked. It is 9" tall from lip to head shoulder. The base diameter is 12". Images of the bell are attached. Thank you in advance to all of your responses.
